I just bought a 01 Pete and i am burning up without the AC!!! The compressor isnt kicking in at all.im going to try and solve this myself. Thanks for you video. I will let you know..
I'm having same problem. I touch that wire with ground it works and kicks on compressor. But does not work from switch on dash. So I'm guessing there is a break somewhere between firewall and switch on dash. So question is do you know which one it is on dash switch? And that wire goes from pressure switch straight to dash switch. Just not trying to tear the vents ect out to trace it.
My man I think you’ve solved my problems can’t wait to check Ty for posting

And also when you jumped wire what did you use for ground on other side inside cab?
