Pcm **** cratered,
Does anyone know how in the world to bypas the pcm and have the ac working off of a toggle, or original button?!

 

If I could get a hold of a pcm I most likely could start repairing one of these for first generation cummins idk if someone has an old one they could send me to give it a try im pretty good with board repairs I work on windmills for a living and I sure that the pcm isn't as complex
