Ok so I checked and the charge is good. I'm really thinking it's an electrical issue this truck had all kinds of wiring problems when I bought it. I currently have the compressor wired to a toggle switch which works great but I want to include a relay so I can include the low pressure switch as well.if I can get that set up and working my next thing will be to do away with the toggle switch and wire the factory a/c switch to the relay instead. But first I need to get the relay wired. Any thoughts on how to do that?
