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.

Do you
have the same problem?

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