A/C relay bypass

[Lazarus]

Ok the dam thing blew Ice cold air with no check engine light. Now it's on it is no longer sending power to the compressor. Checked plenty of 134. No leaks. Even jumped low pressure switch nothing to the clutch. Energized compressor fired right up. Read for a few hours I have a black wire and 3 green wires. No whites or green and black. Took the bottom lonely block jumped to the middle. Compressor fired then blew the AC fuse. Took the lonely to the right block blew computer fuse. Took it to the left and nothing. Diode is broke on compressor plug? Little angry at the moment.

Lol fixed bypassed the relay. Made a you tube video if anyone is interested in a sticky thread. Seems like a constant question with gray answers.

The wiring on these cars sucked and they are getting 30+ years old. I ended up running a toggle switch since mine was butchered and wasn't running the ECM. Don't be surprised if your compressor starts making noise and piles up, I have had a few do that.

I don't think the wires sucked on these cars, the wiring was never meant to last this long so it's just one of those things to replace due to the life expectancy has passed.
