Resistor for that speed or switch is defective

FYI usually high speed on blower bypasses resistors and gets direct B+.

The blower motor and controller module (resistor) are mounted under the passenger side of dash. Remove the plastic cover from the bottom of the dash. The Control module is to the left and back a little. Locate the wiring harness feeding it. You may test the wiring for power with a test light or voltmeter as follows, the red wire in the big connector to the blower controller should have +12 volts on it at all times. If not check the fuse / relay. Then unhook, the smaller two wire connector to the blower motor. Test it for battery voltage across the connector, if you have battery voltage on all speed settings, then your blower motor is bad. If you do not have voltage on all speeds, the blower resistor is bad. Usually the high side or the lower speeds will quit. It is not uncommon for the entire controller to go out either.
To replace the module disconnect the wiring harness connection on the controller from the connector on the wiring harness. Press the locking tab as you separate the two halves of the connection. Use care to not damage the connector from the wiring harness and inspect it for damaged, melted, burnt or frayed wires. Remove the two retaining bolts on the bottom edge of the controller with a nut driver or a socket and ratchet. Pull the controller off the housing and remove it from under the dash. Install the new module with the same screws. Plug the wiring back in and test it.

Air conditioner fan does not go on. Works intermittently. It it's on and not working - it will suddenly go on and work fine. Help! Thanks.


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. May very well be the fuse for the blower as well. The blower connector may be loose. Let me know what you find.

The blower on my a/c quits working, then starts again, then quits...and so on?? is my blower going out or something unplugged?


if it does this on any fan speed it is most likely a bad blower motor, if it inly while on a certin speed such as full high or full low it could be the fan speed resistor located right near the fan motor, screwed into the fan housing

The HVAC blower fan on my 2001 Pontiac Aztec stopped working on settings 1-3 several weeks ago. Last week it stopped working at setting 4 and today it stopped working all together. What is the most likely...


the blower not working on settings 1-3 is the blower motor resistor. this limits the power provided to the blower motor itself to change the speed. at setting 4 it is getting full power. since it quit on 4 also, i would still say the resistor needs to be replaced first, then see if the blower comes back. you may also need a blower motor. if you have a voltmeter you can just turn the switch to 4 and see if the motor is still getting 12 volts. if it is and doesn't run, it needs a blower motor too. if it's not, then its just the resistor

The fan switch is not working correctly - the only time air pumps out of our vents is if the fan is switched all the way to HIGH - any other setting and we get nothing. Any suggestions?


I have a similar problem in my Aztek 2001 as fan switch stage 1 and 2 are not working. In a prvious VW car, I had to replace a resistor module located in the fan blower box under the dash board. I did not yet locate if there is such a resistor module used for various speed selection but will soon try to do it.
