Hey All,

I have an '02 GTP where the rear defrost isn't working. The light on the Heater/AC Control Board just flickers on briefly when the button is pressed.

The only information that I've seen thus far with problems with Heater/AC Control boards is that the "ignition switch" or "fan ignition switch" could be bad. Anyone know if this could affect the rear defroster, too?

Thanks,

Mike
