AC won't blow cold after disconnecting 12v battery

Okay, I'm trying to post a reply but it isn't letting me...let me see if this works.

EDIT: THERE WE GO

That's where I'm running into a problem with my troubleshooting process. As-is, I can't tell if the AC is even being commanded right now. I'm not sure if the button itself is bad, the climate control panel, or if there's a switch/relay somewhere that isn't doing what it's supposed to do.

I did do a search today to see what switches might be hooked into the AC system and found one. It plugs into the AC line itself, and has a number of wires going into the passenger compartment. I wasn't sure if this was some sort of switch that might be involved in turning the AC on and off (I don't see how) or maybe contained a failsafe of some kind that kept the AC off when it's damaged.

There's also the question of that fuse in the inverter itself, as posted above...I have no idea whether I should check that, and if I need to replace it, how I'd even do it.

Ugh. This is bumming me out, especially since all this stems from me trying to fix a snapped lug stud.

 

Exactly what I'm thinking. I'm tempted to replace the climate control panel just to see if there's something screwy in there, at least then I can rule it out. It's weird I'm not getting a light on the button OR an error code, but I don't know how reliable the climate error code system is.

 

Whoops, should have mentioned that. Had the wheel off on the driver side, so I wasn't even over there. I was following the same line of logic until I tracked down the location of the compressor.

 

Yeah, me either. It's all protected by the mud guard that's up in there.

Uploaded the wiring diagram for the AC system if anyone is interested in maybe taking a look and telling me where I might be skipping a step. At lunch, I'm going to go see if the compressor kicks on when I start the car, and then run it to the AutoZone down the street and have them run trouble codes. I'll update if anything comes of it.

Question: Could this be a symptom of a bad AC pressure switch maybe? This website gave me that suggestion, but I wasn't sure if it was a valid route of investigation or not.

 

SOLVED!

Oh, man, is my face red.

It was a freaking wire plug! The damn thing wasn't seated all the way in, and I'm assuming since I live around the worst speedbumps/roadhumps ever, it jiggled out.

Plugged it in, started the car, and held down the AC button. It went cold INSTANTLY.

THANK YOU GUYS FOR ALL YOUR HELP. I never would have figured this out without y'alls patience and input, this place was instrumental toward guiding me to the right place to look.

 

Under the passenger side dash, where the blower is. It's stashed far to the passenger side, way up underneath the glove box. There's three plugs up there, a wide one and two shorter ones. The top shorter plug had pulled out at some point, I'm assuming it wasn't seated correctly during service, and I guess it had just enough of a connection that everything was hunky dory until I drove it around for a few miles.
