    I have a '72 Jimmy that was a/c but took everything air off. My buddy took wires off heater switch and dont remember which goes where, anyone know? Also, any changes need to be done in wiring for just running straight heater? ( ex. relay-ac blower)?

    the guy that had mine before me yanked out the underdash unit and compresor but left everyjthing else and the heater still works good. just make sure you dont have any bare ends laying around.
