Took a long ride today, and it didn't run that great. Took the mechanic's advice and cleaned the maf, and also cleaned the air filter--for now. I'm probably gonna buy a cheapie but figured I try and clean it 1st. Couldn't even see through the filter it was so dirty. Gf is driving it tomorrow, so I guess we'll see if it helped. Pretty sure it'll need a pcm too.

You could try jumping the plug for the low side switch with a paperclip or something similar to see if it forces the A/C clutch to engage. I probably should have mentioned this sooner... Skip to about 1:30 in the video.

Well I just tried jumping that switch connector and got the compressor to come on after it tried 3 times. And it did not sound good. So it looks like I’ll be replacing it. Time to put a parts order in. @clandr1 were you the one that said you ended up with metal fragments from the compressor in your system? I’m hoping mine doesn’t but when it turned on just now it sounded like something was clunking. Hoping this doesn’t turn into a nightmare.

No sir that wasn't me. Sorry to hear that, hope the repair goes smoothly for you.
