Re: 92 c2500 heater control problems

A little more information on this issue. This only seems to happen if I have the defroster on ( or the a/c ). I'm assuming since the air conditioning compressor is activating as soon as a connect the battery, my issue is a relay issue and it's back feeding power to the control cluster. SO, does anyone know where the a/c relay on this is?
