I just purchased a 1998 GMC JIMMY with 115000kms on it and when I turn on the windsheild defroster there is barely any heat comming out even after I have driven several kms. The fan motor works fine but the air is barely warm comming out. Does anyone have any idea what could be the cause. All other cars I have owned the air temperature coming out is hot. This truck's air temperature coming thru the vents is mildly warm. Thermostat seems fine as the temp gage on truck shows normal. Any suggestions?
