Does anyone know if there is a separate fuse for the blower motor? 10 and 20 overload relays which covers over 90% of motor applications. The heavy-duty SUV Ford Excursion was produced from 2000 to 2005. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle. 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? Use the pointy end of the grinder bit to just carefully drill the rest of the material out and take a bit of the galvanized surface down to clean metal.  I suppose you could use a small drill bit for this step too.  I found it quicker to just use the die grinder. 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! Again, the dark spots are flux residue. I replaced it 3X and was starting to think like you but did not know what that part was. My battery is new. 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. I removed and tested the speed resistor, voltage to the blower motor and removed the blower motor.   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. If it's stuck, use a … The blower motor wasn't working on any speed. $30. 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.

AC/heater blower motor relay. Thanks again. 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. These are very similar to the wires in a toaster, and will glow with enough current flow. 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. 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. Locate motor nameplate FLA in the column appropriate for the A bad resistor can cook a fan and a bad fan can cook a resistor. "  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. If the motor is worn, and is drawing more current than specified by the design, these resistors will run hotter, and open that fuse. So check the air filter if there ever is a next time. It doesn't work on any speed. Ya, like I was saying, I replaced the blower motor and the VBC. Cigar lighter (power outlet) fuses in the Dodge Ram 1500/2500: 2002-2005 – fuses №25, №29 and №42 in the Integrated Power Module. If the fuse is blown, replace it and then try the blower.

Did you make this project? Thanks! F16 6 years ago When the motor gets old and tired it will draw more current through the wires than a new motor. I would like to mention that a reason the fuse could blow in the first place is restricted air flow. I have a 2003 Dodge Caravan. I checked the interior fuse panel and didn't see anything blown. The electronic controls seem to be working (display, dampers, etc.) Just set the crimp on the area. on Introduction. 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. The blower in the back works, but I don't have heat there (that's another story). VERY good tutorial !! The blower motor in my 2008 chevy cobalt does not work. That was the problem, thanks! I have wagon r 2009 model lxi. 6. Also, check for voltage at the fuse. I am a hard working individual. Air Bag Module, Climate Mode Switch (Blower Relay) 23. fuse 10A mini. 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. More current means more power dissipation with less cooling air flow and you have a recipe for heat rise. 8. Fuse box diagram (location and assignment of electrical fuses and relays) for Lincoln Town Car (2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011) I changed the resister, and the connecting harness that connects to it. Replaced motor, still doing same. 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 . Fuel pump (FP) relay. 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. Step 1 Here are the locations and a guide to help you test As others have mentioned, repeated failures would indicate too much heat from these resistors. The blower motor resistor is located in the heater box area, which is under the dashboard on the passenger side. Good luck! Since some furnaces can require a lot of electricity, homeowners must ensure that they have an adequate electrical system to support the furnace. Horn relay/alarm system horn relay. I have a feeling it will keep working for a long time too because of a better quality thermal fuse. It does not work in any position. 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. Blower stopped working last Thursday, It came back on Friday after I wiggled the blower motor resistor, went back out Saturday. It cranks too slow and doesn't start, if i drive it a bit longer. Runs on all speeds for approximately five to ten seconds then fuse blows. 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. 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 … F15 (30A) Head lamp washer pump. The interior fan is powered through two separate fuses and a blower motor relay. Remove the panel cover to access the fuses. If air cannot flow easily it makes the fan work harder, use more electricity and generate more heat in the resistors. 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. Accessing the fan blower's motor or replacing the fuse should only take about five minutes. 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 blower motor relay on your Chevy vehicle is essential for the operation of the blower. If the blower works when you change the fuse, you may not be out of the woods yet. Check for voltage and ground at the blower motor wiring, if good voltage and ground with no blower action, suspect the blower motor. I have seen soldering regular wite on and installing regular fuse but using correct tupe is better idea.
