I have a 2003 Dodge Caravan. Check Voltage and Ground at the motor. Since some furnaces can require a lot of electricity, homeowners must ensure that they have an adequate electrical system to support the furnace. Heat up your soldering iron and tin the crap out of the surface.  My goal was to add just enough solder to fill the holes over and provide a nice shiny surface.  I know it doesn't look like it in the picture but its kind of blurry and any dark spots you see are flux residue.  I used lots of flux to ensure good solder flow. If your map light, stereo, turn signals, heated seats, headlights or other electronic components suddenly stop working, chances are you have a fuse that has blown out. The video above shows how to check for blown fuses in the engine bay of your 2009 Nissan Rogue and where the fuse box diagram is located. 10. Remove the panel cover to access the fuses. Not Used. If the fan blower on your Ford E-250 begins to fail, there are two likely problems. The blower motor resistor is located in the heater box area, which is under the dashboard on the passenger side. I replaced it 3X and was starting to think like you but did not know what that part was. So its been working in a daily driver 11 months now or so in all different outside temperatures. $1.50!! 3. If the blower works when you change the fuse, you may not be out of the woods yet. Maybe under the hood? One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. Checking applicable fuses is good. We use cookies to ensure that we give you the best experience on our website. 2002-2005 – fuses №2 (Power point – floor console), №3 (Power point – 3rd row), №4 (Power point – instrument panel), №5 (Power point – right rear quarter) and №12 (Cigar lighter) in the Passenger compartment fuse box. My blower motor is not working. The fuse panel is located below and to the left of the steering wheel by the brake pedal. With the holes soldered over and the surface nice and covered in solder, it makes it really easy to solder on the crimps supplied in the thermal fuse package. Engine control (EC) relay. In my case, I had a rodent nest in the blower box. Cigar lighter (power outlet) fuses: If you have multiple resistor packs to do, I would suggest just knocking them out while you're doing it.  It only took me a matter of 15 min from start to finish.  The longest waits are waiting for your package of thermal fuses to arrive, and waiting for your soldering iron to heat up. So i eotk in a shop. 105. fuse 40A cartridge-j. The interior fan is powered through two separate fuses and a blower motor relay. VERY good tutorial !! Check here for special coupons and promotions. Fuse box diagram (location and assignment of electrical fuses and relays) for Lincoln Town Car (2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011) 2000-2001 – is the fuse №3 (Cigar Lighter) in the Instrument panel fuse box, and fuses №7 (Floor Console Auxiliary PowerPoint), №9 (Left Rear Quarter Auxiliary PowerPoint) and №11 (Cargo Auxiliary PowerPoint) in the Engine compartment fuse box. The fuse panel is located below and to the left of the steering wheel by the brake pedal. 5. As others have mentioned, repeated failures would indicate too much heat from these resistors. 2. Did you make this project? F15 (30A) Head lamp washer pump. Very good job. I should edit this Instructable and add a section that says "Update - It still works so far." You will find the resistor in the large squarish tube that leads to the center of the dash from the blower motor housing (right to left on an american vehicle). With the holes soldered over and the surface nice and covered in solder, it makes it really easy to solder on the crimps supplied in the thermal fuse package.  Just set the crimp on the area.  I used a bit of flux just to make sure and then heat with iron and add a bit of solder and you got it held in place.  Again, the dark spots are flux residue.  I assure you there are good solid solder joints there.  When I'm all finished I use a remover to clean it up.  Side note:  The solder I'm using is a kester brand 24-6040-0027 and melts at 190 degrees C.  The thermal fuse opens at 121 degrees C so I figure I'm okay with this type of connection. Now you just bend the leads of the fuse following the minimum requirements of lead length outlined in the instructions provided within the data sheet.  Insert the fuse into the crimp barrels and crimp them in.  Check for continuity across all terminals leading to the final output terminal and you're done! If you continue to use this site we will assume that you are happy with it. Just set the crimp on the area. Either the motor is malfunctioning and will need to be replaced, or more commonly the fuse has blown out. A bad resistor can cook a fan and a bad fan can cook a resistor. $30. (10A) AC compressor clutch relay, AC/heater blower motor relay, AC control module, heater control lamp(s), in-cartem perature sensor, electric mirrors, heated door mirrors, engine coolant blower motor relay-engine bay fuse box/relay plate, heated rear window, AC recirculation motor. Reply Order Ford F150 Relay - Blower Motor online today. In this case the blower motor fuse is identified as F7 20A 250V and is located in the upper right end of the circuit panel. When the motor gets old and tired it will draw more current through the wires than a new motor. The heavy-duty SUV Ford Excursion was produced from 2000 to 2005. The blower motor depends on a properly functioning 15-amp fuse to regulate the power flow that controls the blower motor speed. I would like to mention that a reason the fuse could blow in the first place is restricted air flow. More current means more power dissipation with less cooling air flow and you have a recipe for heat rise. I used a bit of flux just to make sure and then heat with iron and add a bit of solder and you got it held in place. what could be the issue? for my resistor assy. Engine compartment fuse box (if equipped) The power distribution box is located in the engine compartment. vs. Glad you liked it! 7. In this article, you will find fuse box diagrams of Ford Excursion 2000, 2001, 2002, 2003, 2004 and 2005, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay. I have a feeling it will keep working for a long time too because of a better quality thermal fuse. Now starting to scratch my own head, I decided to pull the old resistor pack he had replaced out of the box to see what actually went wrong.  Normally I'd be looking for a broken connection or a burnt up coil.  This one is the resistor pack you see in the photo with my multimeter in the background.  It looks relatively in good condition...so what gives?  Continuity check time just for good measure.  The way this circuit works is all on the ground side.  12 volts is always present at the motor, and the switch in your dash provides the ground.  On speeds 1-3 the ground is re-routed through the resistor pack and on high speed it bypasses the resistor pack and the motor gets full voltage.  So effectively, the lower the voltage, the lower the speed.  The way the resistor pack does this is by shortening or lengthening the circuit through the coils to add or subtract the amount of resistance it takes to get the speed you want.  So naturally, three speeds, four pins.  One for each speed and one that heads to the motor.  I start my continuity check across each coil and everything is fine until I reach the final pin.  I check my meter "beeeep"...then check again...nothing.  Then I realize there had been a cylindrical bullet shaped thing I didn't recognize stopping the current from passing through.  Finally!  Something wrong!  So what is it? Does anyone know if there is a separate fuse for the blower motor? Selecting Fuses for Motor Running Protection Based on Motor Actual Full Load Currents 6 Better protection is achieved when fuse ratings are based on motor actual FLA obtained from motor nameplates. Locate motor nameplate FLA in the column appropriate for the Tip Check So we decided that maybe the plug-in that goes to the resistor pack was corroded just enough to block current from going through it.  I replaced that, solder and shrink tube, (the only way to make wire connections in my opinion) and plugged it in with tons of dielectric grease on it expecting it to fix the problem.  Well it didn't hurt, but it didn't fix it. Trailer Tow Battery Charge Relay, Turn/Hazard Flasher, 4x4 Solenoids, 4x4 Relays, Overhead Console, 4 Wheel Anti-Lock Brake System (4WABS) Module ... 4x4 Shift Motor & Clutch. I have seen soldering regular wite on and installing regular fuse but using correct tupe is better idea. On the automatic temperature control system they further complicate the system by using a module. I believe I did the mod in Jan 2014. Share it with us! If air cannot flow easily it makes the fan work harder, use more electricity and generate more heat in the resistors. on Introduction. I removed and tested the speed resistor, voltage to the blower motor and removed the blower motor. Now the instructions say to use the crimps and only make mechanical connections.  By no means, do you solder this guy on...as tempting as it may be.  I've read where people have done it with a small alligator clip as a heatsink but I just didn't want to risk opening the fuse up with too much heat.  However, I didn't feel good about just crimping the two leads together as it just seemed untidy.  So, this is my spin on it.  Use a die grinder or equivalent to remove the original crimps down to where the lead breaks in two and the fuse will fall off. 8. If the fuse is blown, replace it and then try the blower. I also checked the fuse and the fuse is good also, there is power coming from the connector going into the resister, but the pigtail that comes from the resister and plugs into the blower motor … So why do these fuses blow in an otherwise normal circuit?  Why wouldn't the main circuit fuse blow instead?  Well that's the question I have and the only logical answer I have is:  Heat.  Heat either caused by poor airflow across the resistor pack resulting in poor cooling, or heat caused by a higher amperage draw from a worn out motor with poor lubricated bearings/bushings or worn brushes.  If the motor was serviceable, that would be the next route I would take.  Seeing as it isn't, and this fixed the problem very cheaply with spare resistor packs resulting from the idea that the more practice, the better, then this is the last I'm going to worry about it.  That is unless the problem occurs again and again with increasing frequency.  Then it almost has to be a problem with a faulty motor I would think.  That's all for now.  I tried to be as detailed as possible.  I hope this instructable is enjoyable and helps someone troubleshooting with the same predicament.Â. F16 1 year ago. I didn't know what that thermal fuse gizmo was, either. The blower motor is powered by a fuse-like device called a relay. The blower motor resistor was a little rusty.I inspected and found no burned or melted wires anywhere , at the inside three way dash switch , at the blower motor and at the resistor.I know the air bag is tied into the same fuse , I must have replaced the fuse 12 times . Free Same Day Store Pickup. I tried to find a fuse to check but did not find something labeled for blower motor. Have you ever started your car up in the morning only to realize that your heater fan doesn't work on any of the slower settings but does work on high speed?  Well, my friend did.  In, fact, this occurrence happened to him not once, not twice, but three times.  I'm not completely sure of the construction of different car manufacturers' resistor packs, but odds are, if you own a Ford, this may apply to you.  This is the basis for this instructable. That was the problem, thanks! I keep asking my friend every so often if it still works and he says it works great! AC condenser blower motor relay 1. but the blower motor just won't come on. 106. fuse cartridge-j. I also checked the voltage and it had 5v running to it. even at $1.50 a piece, your time is worth more than the headache. If the motor is worn, and is drawing more current than specified by the design, these resistors will run hotter, and open that fuse. Is there a part number for the thermal fuse? When you get yours done you should post an "I Made it" comment back here so I can see it. Thankyou. It doesn't work on any speed. If the fuse blows right away, your car may have a bad blower motor or some other problem in the system. We have had issues chassing these types of things. Ya, like I was saying, I replaced the blower motor and the VBC. Thanks! Good, helpful article. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle. 6 years ago on Introduction. Thankfully, it is fairly simple to tell if the relay is malfunctioning and to install a replacement. But I'm pretty sure its the Relay. Replaced motor, still doing same. Attach the clip lead of the test light to a good ground like a bolt screwed into metal, and touch the sharp probe end to the terminals on the fuse. Cigar lighter (power outlet) fuses in the Dodge Ram 1500/2500: 2002-2005 – fuses №25, №29 and №42 in the Integrated Power Module. 2006-2009 – fuses №1, №38 and #40 in the Integrated Power Module. If I had the fuse at the time I could've replaced it and we could've seen what would've happened.  The next morning we went to a different auto parts store and got the same part, this time with the correct fuse rating.  Replaced the part and everything was good until...about two months or so later.  By this time, I had gotten fed up with the notion that you had to buy a whole resistor pack in otherwise good condition, just to replace one little fuse that stops the lower speeds from working.  I had ordered some fuses and gave it my shot at replacing them.  I've read where people have replaced this said fuse with success but I couldn't find any, step by step process or pictures of how they did it. Locate the fuse for the blower motor in the owners/service manual. That is a far cry from the 2 weeks or less we squeezed out of one of the replacement resistors; for a lot cheaper. Relay click. https://www.youtube.com/watch?v=irgvh_UJHMo. Blower motor blowing fuses. The relay is underneath the glovebox too. The part I ordered is from NTE Electronics.  It is the correct 121 degree C value and it comes with little crimps and instructions.  The part itself cost roughly $1.xx...I ordered 6 with shipping for around $10.  A new resistor pack at this time cost somewhere from $16-20 from aftermarket suppliers.  Like I said earlier, I won't mention names...but they rhyme with "crappa" and "autotone"...  I never did check with original Ford parts, but I'm sure it would've been twice that.  Bare in mind I had 3 resistor packs to try it on and I could easily screw one of them up haha.  So you could say I'm potentially saving my friend quite a bit of money here. Air Bag Module, Climate Mode Switch (Blower Relay) 23. fuse 10A mini. Also, check for voltage at the fuse. It does not work in any position. AC relay. The blower motor wasn't working on any speed. Fuel pump (FP) relay. Check.   So a little background of the problem before I jump into this.  The heater fan in a 98 Ford Explorer stopped working completely for my friend.  He bought a replacement fan and all was good for about two weeks.  Then the fan stopped working on all speeds except "high. Step 8 Pull the fuse out of the fuse clips. The Pontiac Grand Prix has a blower motor that is regulated with a fuse located in the fuse panel inside the glove box. Just another shot of the finished product.  It may look a bit sketchy but I assure you this method works and works well.  The reason I did it this way is because I can easily desolder the old crimps and discard the old fuse.  Resoldering the replacement fuse would be a breeze.  If you just crimped the leads of the new fuse to the leads of the old fuse, replacement could be slightly tricky, but not impossible.  Personally I'm just more comfortable with soldering.  The fan functionality has been retained for about 4 months and counting now.  I can only attribute it to the higher quality thermal fuse. They control the HVAC circuit with a switch. 4.

Again, the dark spots are flux residue. 10 and 20 overload relays which covers over 90% of motor applications. The blower motor relay on your Chevy vehicle is essential for the operation of the blower. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown. I changed the resister, and the connecting harness that connects to it. If the relay is blown out, you will need to install a new one is soon as you can. Blown fuses usually result either from an appliance putting too much strain on the fuse or by an electrical short in the system. The blower motor in my 2008 chevy cobalt does not work. My battery is new. you will breathe easier in more ways than one. Starter motor relay. Check for voltage and ground at the blower motor wiring, if good voltage and ground with no blower action, suspect the blower motor. Whenver i run it around 20Km and in case if it stops or i remove key and start again, engine feels very hard and either hardly starts or dont starts. Climate Control Front Blower. So check the air filter if there ever is a next time. Blower stopped working last Thursday, It came back on Friday after I wiggled the blower motor resistor, went back out Saturday. The blower in the back works, but I don't have heat there (that's another story). Fuse box diagram (location and assignment of electrical fuses and relays) for Chevrolet (Chevy) TrailBlazer (2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009). I am a hard working individual. The electronic controls seem to be working (display, dampers, etc.) If it's stuck, use a … There is one other thing that I did. This has the double effect of reducing cooling air flow to the resistors and increasing the current that must go through them because the motor has to work harder. Accessing the fan blower's motor or replacing the fuse should only take about five minutes. I went ahead and replaced the blower motor resistor and cabin air filter, but it is still completely dead. I just unhooked my glovebox, folded it down, and listened for the … Step 1 Fuel filter heater relay. I replaced the cabin air filter this time and was it a clogged mess! even mechanic failed to find same. All automotive fuse box diagrams in one place. Thanks again.

I am into electronics and mechanics mainly but can get into anythi…, RC Arduino Domino Layer With Bluetooth App Control. It cranks too slow and doesn't start, if i drive it a bit longer. Good luck! The power distribution box is located in the engine compartment. At done point you chase back and forth until you use high tech (and a pain to use) equipment to prove a failing fan ehen resistor is shot or you guess and do both. I have wagon r 2009 model lxi. 6. "  He bought a replacement resistor pack from an aftermarket company.  I won't mention any names but its a major auto parts store.  All was well for about a week and then the same thing happened again.  So I get a call from my friend a little bit annoyed and confused about the whole problem.  We go through the possibilities because surely it wasn't the resistor pack, that was just replaced... it could be a bad connection, bad relay, bad switch, blown fuse...etc.  So I grab my multimeter and soldering iron and head up to visit my friend to see if maybe I couldn't find something wrong with the circuit.  All fuses that pertain to the circuit.
