Thread: hello- have intermittent heat/ac blower problem.

Just looking around it seems like I don't get the air out of the inside vents like I think it should. Maybe its just the way it is. It doesn't seem to put out more air in recirculation mode with AC on either.

Like a dead blower fan? It's probably the resistor gone bad.

Make, model, and year of your car? Some models have a bad design flaw that dumps rain water from the windshield right into the air intake and right onto the blower or resistor, killing them. All because GM is too cheap to send in $5 upgraded deflector piece to fix this.
