A/c clutch circuit issues
I’m trying to run down a bad wire. My clutch will not engage when A/C is on. Does anyone have a picture that shows exactly where PCM connector A and climate control unit B is located under the dash. Also my repair manual makes reference to fuse 58 (30a) in the under hood fuse/relay box. That’s not listed in the car’s manual or on the fuse box lid.
I’ve replaced the compressor and pressure switch. I put a jump wire on the relay to engage the clutch manually so that i could charge the system. Any help with wiring specifics would be awesome.

I would rule out pressure sensor, fuses, and relay before chasing wires.
Download the service manual HERE. All the info you need to get you started.
If you have access to a bidirectional scanner you can manually command the clutch to help with diagnostic. Let us know what you come up with.

I checked all the fuses and swapped the relays with known good ones. I have an electronic copy of the manual but it doesn’t describe where exactly the connectors are located.
