SOURCE: where is the heater blower motor resistor located

Just a picture to confirm what coly_coli posted, no new information

This is the wiring harness for the blower motor resistor, the actual resistor is mounted in the blower duct. If you follow the harness to the left ( towards the driver's side ) it is on the connector on that end.

SOURCE: Heater fan only works on high speed 4.

sounds like the switch is bad. Test the power coming in to the connector and use jumpers to get the fan to operate at all 4 speeds. if it works then it the switch.

SOURCE: Lincoln 2000 town car Blower doesn't work at HI-MED-LOW speeds...

it is called blower motor resistor , should be close to blower motor , you will see a plug type connector with two screws , remove the screws and there should be a resistor inside the cover for the motor, swap with new and reassemble

SOURCE: 2003 Chevy Malibou RU872 resistor location blower switch relay

For location and replacement of the BMR. Remove the shroud below the glove box, 2 screws and a snap-pop fitting. Be careful of the courtesy light. Remove the blower moter and disconnect the power harness - - you'll need this extra room to work with. 2 more screws, same size, 7/32, 6.5, 7or 8mm on some, that holds the blower motor resistor in place. This replacement part is less than 40 bones at most parts store. Unplug, replace, re-install, test and you're on your way with about 2 hours of slow paced effort in your own driveway. Typical cost at a garage/dealer - up to $400.

SOURCE: 2002 Chevy Impala Blower resistor location

It is on the passenger side, you have to remove the black plastic kick plate, below the glove box, to expose it (held in place with 2 latches and 1 push pin). The resistor is in front of the blower motor ( sandwiched between the motor housing and the firewall) it is tricky to get to, i think when i changed mine i didnt replace all the screws as they were difficult to remove and even harder to replace. Good Luck, Mike

2003 jETTA Fan only works high speed. For AC compressor runs but no fan other than when switched to high speed at which time the fan runs at high speed but AC switches off.


a resistor went bad for your blower motor.It is located by the blower motor on a circuit board.You can get the replacement resistor at Radio Shack and solder it in.This fixed my problem

Nothing coming from the vents when you turn on the a/c, heater, or defroster


You can jumper the fan motor to make sure it runs and if it does then look at the switch or resistor. You can also remove the resistor and omh acrossed it to make sure that it hasn't blown the fuse on risistor.

I have a 2003 monte carlo. Heat and a/c work but when you turn the fan speed control nothing comes out of the vents


This sounds like you may have a bad blower motor or a bad blower motor resistor, the most common is the resistor. i will enclose a picture of the resistor, if you look on the pass/side under the dash to the right you will locate the blower motor, a good test to be sure would be to turn on the blower and test for power and ground at the blower,one wire will have power and the other ground, if you have both then the blower is bad but if you only have one of the two then its the resistor, some resistors control the power feed and others the ground feed this is how the speeds are controlled.most newwer cars are ground controlled.the resistor is located near the blower and is bolted to the heaterbox, if you locate the blower and follow the wires from the blower it will lead you to the resistor.hope this helps,johnjohn2_158.gif

A/c blower wont work. what should i check after fuses?


Might be the Resistor pack located close to the blower. It has a flat connector with 4 or 5 wires, and two small screws holding in the duct. It may be a crispy critter. It happens... The blower moves air across it to keep it cool. The blower motor may be bad as well, or possibly the fan speed switch. Let me know what you find.

the module that you described at the end of where the fan plugs into has probably went bad. when it dies it closes the contacts in the module and power is on all the time. good luck

The air conditioner doesn't turn on. If I turn the knob over to the vent, it gets warm, but the fan isn't running at all


So your saying that the blower motor will not blow anything hot or cold.

You probably need a new blower motor . Its not likely that all speeds would go especially high speed since all the other speeds go threw a resistor and high speed is direct B+ from the battery. Start therebefore I have you testing a/c parts. Keep me posted.

My low speed fan doesnt work on my ford f-150 1995 truck


The blower motor resistor is responsible for blower speeds less than high or full. The resistor is located on the passenger side underdash next to the blower motor, should be 2 screws and a wiring harness, replce the resistor and see if your fans speeds work correctly. Hope this helps, let me know.

Vent fan only works when set to 4


Hi.....
On your Vehicle the problem for the FAN speed is NOT the FAN switch.
99.9 % of this problem on cars is the BLOWER MOTOR RESISTOR.
The blower motor resistor give the speed to the Fan.
But on High speed the switch make a By pass of the switch using a Relay for the high speed.
The Blower motor resistor, is located Beside of the Blower motor On the passanger compartment.

If you replace the blower motor resistor you have 99.9% of this will solve your problem.

I'm a Mechanic.

I hope this help on your problem.
Thank you for use fixya...
