If you have a 12V Ign source feeding into the heater control can you test the circuit that turns the "heat" or "a/c" on and see if either is working? From what you typed the answer to my question is "no". That said, if you turn on the "heat" or "a/c" does the blower motor function? If no I'd guess that you have something wrong with the heater control or 12V is applied to the incorrect terminal. Can you supply a copy of the wiring diagram? That would be very helpful. Please don't make me get up and walk across the living room.



If I turn the controls to either heat or A/C the vacuum operated controls work, but the fan doesn't turn on.

I need to find the wiring diagram so I can start jumping some things around.. Anyone have one postable?

Thanks,
