I feel sort of foolish asking this question being the operation of the heat/cool lever is simple. Mine is working backwards. When I move the lever to cool, it blows warm. When I move
it to warm, it blows cool. The cable can only go on one way and it connects direct to the lever on the heater box. It's moving the lever left and right, so I can't understand how it can.
work backwards. There is a vacuum switch that the lever contacts when in the cool position, which I assume has to do with the AC. The first pic is in the heat position and the second is in the
cool position.
