10. Runs on all speeds for approximately five to ten seconds then fuse blows. Climate Control Front Blower. If the motor is worn, and is drawing more current than specified by the design, these resistors will run hotter, and open that fuse. Here are the locations and a guide to help you test $30. 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. I am a hard working individual. 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 … On the automatic temperature control system they further complicate the system by using a module. Replaced motor, still doing same. I have wagon r 2009 model lxi. Maybe under the hood? 106. fuse cartridge-j. Did you make this project? It doesn't work on any speed. 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. 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.

Order Blower Motor Relay for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. 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. Order Ford F150 Relay - Blower Motor online today. Not Used. Thankfully, it is fairly simple to tell if the relay is malfunctioning and to install a replacement. In my case, I had a rodent nest in the blower box. 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. I believe I did the mod in Jan 2014. 10 and 20 overload relays which covers over 90% of motor applications. As others have mentioned, repeated failures would indicate too much heat from these resistors. 6 years ago Fuse box diagram (location and assignment of electrical fuses and relays) for Lincoln Town Car (2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011) Tip More current means more power dissipation with less cooling air flow and you have a recipe for heat rise. Either the motor is malfunctioning and will need to be replaced, or more commonly the fuse has blown out. Check Voltage and Ground at the motor. 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.

"  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 blower works when you change the fuse, you may not be out of the woods yet.   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. I removed and tested the speed resistor, voltage to the blower motor and removed the blower motor. Good article thanks. Fuel pump (FP) relay. I changed the resister, and the connecting harness that connects to it. even mechanic failed to find same. It does not work in any position. So i eotk in a shop. 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! Remove the panel cover to access the fuses. I replaced it 3X and was starting to think like you but did not know what that part was. on Introduction. Glad you liked it! 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? My blower motor is not working. Thankyou.

The fuse panel is located below and to the left of the steering wheel by the brake pedal. The blower motor is powered by a fuse-like device called a relay. 6 years ago A bad resistor can cook a fan and a bad fan can cook a resistor. Cigar lighter (power outlet) fuses: It cranks too slow and doesn't start, if i drive it a bit longer. The interior fan is powered through two separate fuses and a blower motor relay. I tried to find a fuse to check but did not find something labeled for blower motor. The blower motor wasn't working on any speed. When the motor gets old and tired it will draw more current through the wires than a new motor. If the fuse blows right away, your car may have a bad blower motor or some other problem in the system. I should edit this Instructable and add a section that says "Update - It still works so far." There is one other thing that I did. The Pontiac Grand Prix has a blower motor that is regulated with a fuse located in the fuse panel inside the glove box. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. 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. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown. Starter motor relay. Step 1 While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle. 7. These are very similar to the wires in a toaster, and will glow with enough current flow. I just unhooked my glovebox, folded it down, and listened for the … 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. AC/heater blower motor relay. So check the air filter if there ever is a next time. If the relay is blown out, you will need to install a new one is soon as you can. 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. Check here for special coupons and promotions. Check for voltage and ground at the blower motor wiring, if good voltage and ground with no blower action, suspect the blower motor. 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. I replaced the cabin air filter this time and was it a clogged mess! but the blower motor just won't come on.
