I had the serpintine belt replaced in my 1996 Bonneville, and every since
then my heating and cooling isnt working properly. The blower works
fine!..If the blower decides it doesnt want to blow heat it doesnt. The
climate control readout blinks and it blows cool air. If it does decide
to blow heat the climate control readout is fine.
The 2 main electrical components have been changed. Nothing helped. Still
just blows heat when it feels like it. It acts like there is a heater door
sticking shut or something. Nobody came seem to find that to be a problem
though? Any help would be appreciated. Thank You
