Take a shot at trying to troubleshoot air conditioning problems in your Pontiac Grand Am before making a costly and time-consuming trip to the dealer or a mechanic. Sometimes air conditioning problems in an automobile can be an easy fix, even for those of us who know nothing about cars.

Troubleshoot Air Conditioning
Start the engine of the car and allow it to run for a few minutes. Adjust the climate controls. If they do not feel right, then the problem is probably in the control panel. If the controls feel fine, but have no effect on the air then it is probably a blown fuse. If you cannot hear the accompanying blowing sound when the air is turned from low to high, then the problem is in the blower motor.
Disconnect the black negative battery cable first when looking for the blower motor. Remove the trim panel and unplug the electrical connectors from the blower motor. Unscrew the retaining screws and remove the blower motor and fan.
