The climate control fans won't come on, and without them I can't use the A/C. I checked all the fuses and they are ok. How do I fix this problem.


Inspect for burnt wiring connectors at the switch and the blower motor, replace all that are damaged and the switch as well.

The ac/heat fan only works on the high speed


The blower resister located near the blower motor is bad,this is what controls the speeds,except the high setting.

2003 Alero, heater blower only works on the two highest position?


The blower motor is located on the passenger side of the vehicle next to the blower motor. Run the fan on high and listen for the blower motor location if in question. The resistor will be mounted into the heater case and held in by two screws.
Good Luck
