Hello, my name is***** if you jump pin 87 to pin 30 that should force on compressor. Does it?
Pin 30 should have voltage at all times. If so then replace the dark green wire that goes between fuse box and compressor. Plain and simple compressor should turn on when jumping pins so they either do not know what they are talking about or you have two separate issues. Let me know how it goes or if you have more questions. Here is a wiring diagram of system. Thanks.
A paperclip would work fine so that shouldn't be the issue. I'd start by figuring out why compressor doesn't turn on as described above and if you still have issue test wiring between controller and PCM, if good then replace PCM. It definitely sounds like you have a broken dark green wire as of now but you need do above tests. Let me know if you have questions or run into questions, you can reply to this answer at any time without additional fees. Thanks.
Just going to have to do the tests and go from there, without testing it could be too many possible options. But if you jumped relay correctly we know one issue can only be wiring, connection, or blown fuse. Let me know if you have questions, thanks.
No, the abs fuse wouldn't cause this. Only fuse that would stop pin 30 from having voltage is the 10 amp AC fuse. Let me know if you have questions, thanks
Let me know how it goes or if you run into questions. Thanks.
Good to hear the wiring problem was found. It does sound like control head should now take care of the problem. Let me know how it goes, thanks.
Good to hear things are being taken care of. Let me know how it turns out or if you run into more questions. Thanks.
