wiring diagram for A/C environmental control 1986 K20

[elyon]

Any one have a wiring diagram for the A/C control? I was replacing my Speedometer last Fall and I must have disconnected a wire behind the dash, as I have no voltage going on to my compressor anymore. Getting warm out. Time to fix it.

Check the fuse...? Check the freon charge. If it's low the compressor will not come on. I have a factory electrical manual, I can check it for you tomorrow. Is your rig a pickup?

I just saw you're here in ENC. I'm in Havelock.

Thank you sir. My A/C system is fine. I chase the wire from the compressor back to the pressure switch. No voltage coming through the fire wall. I checked the fuse as well. Pretty sure I disconnected a wire under the dash.

o.k. here's a pic of my 1990 burb wiring schematic. I can't imagine it's changed that much over an 86. btw, I have an 86 'burb too. Hope it helps!

Thank you for taking the time to post this. Unfortunately, I can't see the schematic for some reason. It just says

I even went to my computer thinking it might be my iPad. Oh well. I appreciate you trying.

Thank you!
