1992 Pontiac Sunbird 2.0l mileage: 135,000. All of a sudden the heater motor stops blowing. I ran a hot wire to it and it works, fuses good, grounds good. All I can figure is the switch. Anything I might have missed? I'm an old VW'er we never have these problems, but my wife wants to be warm.

In the heater duct there is a resistor for different fan speeds, which may have failed. Also, check the blow fan relay.
