Pin 86 has power key on
Pin 30 no power
Pin 85 no ground from ECM
Pin 87 no power to compressor
I did get the compressor to come on by jumping pin 30 with power and grounding pin 85
My question is, what is likely the problem? The fuse box underhood could it be a burnt wire under there? Or a burnt wire coming from ECU to relay? If I run a wire to a toggle switch in place of ECU ground will the compressor still cycle on and off? I also noticed no power to high pressure switch and no power to no power to low pressure switch. I have ground on both.
What sends power to high and low switches?
have the same problem?
