I have a 1992 Grand Am SE with a 3.3l in it. I am having problems with the car heating very little. It is weird cuz the drivers side vent/defroster/heater has warm air comming out of it but the passenger side vent/defroster/heater has cold almost like outside air comming out of it. I live in Wisconsin and the weather has been terribly cold here and i would like to get this fixed. As per some of the other threads that i have read on here i am beginning to think that the heater core might be slightly plugged, idunno for sure and don't really have the resources to do it at this time untild the weather warms up. Any and all insight is appreciated and hopeful will help me to get this problem fixed.
Thanx,
Jeremy
