Pontiac Grand Prix AC/Heater Fan issue
No matter what settings I put the fan on, I get nothing more than just a trickle of air out of all the vents (defog, head, feet). When I change the speed settings, the fan gets louder, like its trying to blow air harder, but still nothing more than a trickle of air from the vents. Changing the vent selector doesn't affect the airflow out of any of the vents. If I turn on the AC, it seems like the trickle of air does get cool eventually, but not nearly enough to make the car comfortable.
Has anyone seen this issue, and can point me in the right direction to fixing it?
