SOURCE: Low speed ac blower motor does not work. Other

The heater blower motor has a blower resister. its in the heater box next to the blower motor, above the passengers feet. The bottom of the dash has a cover hold on with a few screws. the resister has a 4 or 5 wire plug and is heald in with 2 bolts, remove the connector then the bolts and it'll slide out. The new one may have to come from the dealer and have your VIN ready when you call. They'll have it or can get it in one regular day

SOURCE: Front heater blower low speeds dont work

if you have just high speed, you need to change resister, usually in plenum case to keep it cool. If it goes again, change motor, it is drawing too much current

2008 Impala blower don't work


You probably have a bad blower motor control module .First check the Batt. 4 fuse 30amp in the under hood fuse box .
Blower Motor Control Processor The blower motor control processor is an interface between the HVAC control module and the blower motor. The blower motor speed control, battery positive and ground circuits enable the control processor to operate. The HVAC control module provides a pulse width modulation (PWM) signal to the blower motor speed control processor in order to command the blower motor speed. The processor supplies 12 volts to the blower motor through the blower motor voltage supply circuit. The control processor uses the blower motor ground or low reference as a low side control to adjust the blower motor speed.

How do I replace blower motor resistor?


U are on the right track. But check this out - is the low speed on the blower the only thing that is not working? Could be other things, such as lights that you are not aware of.

On some cars the low speeds for the blower work thru the ignition switch. If something is wrong with the switch the fan will work on high speed only but the lower speeds are inoperative.

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

The air stopped working in my 1996 Lexus LS400 fan quit .....no power at all. small fuses are ok how do you check those big breakers or fuses


Did the fan quit only on low speeds or all speeds? If only on low speeds, the resistor is bad. Good news is that it's a cheap part. Run it on high until you can fix it.

Why does blower fan speed switch lock-out off and low speed positions on 1998 chevy silverado? It stopped working altogether then I replaced a 10 amp fuse and now only medium high and high will work but,...


Sounds like you may have a bad blower motor resistor.  When they go bad, they usually wipe out all speeds except high.  But could knock out just one or two of the speeds.  It should be located near the blower motor.
