AC just quit blowing cold all of the sudden
 

And the compressor doesn't appear to be coming on when I turn the AC on.

Troubleshooting tips?

Worst about all of this is my 2022 C8 Vette was supposed to be here by now. So I've either got to fix this and sell it on my own or take the loss in the form of trading it in. FML

Does the light come on? I mean it sounds like you are going to have to do some multi-meter testing. You checked the fuses already I assume?

Yes, light comes on and I have checked the fuses.

Replacing the compressor is only $200-300 but I would check for loose wiring first. I think there is only one wire (maybe two) that run to the compressor. Make sure you are getting 12v to it when the switch is on. That should engage the magnetic clutch.

if the refrigerant pressure is too low the system won't engage.

I'll check this stuff out tomorrow. Thanks!

There is also a secret cheat code to switch it to a diagnostic mode. Look in the service manual for the dual climate control. It's buried in there. Will check back later tonight when I get home.

That would be awesome!

First thing to do is put gauges on it and check pressures. For it to not come on at all it would have to be less than around 5psi on the low side. 2nd you could check to see if you are getting voltage to the clutch/clutch resistance. Once you know those items you will know what part of the system to troubleshoot further.

Alright. Look for the manuals link in my sig. Here's a screenshot of the menu drilled down to the important pages. You'll see what I mean pretty quickly.

Grady's on point. That really is the essential first step.

YIKES! After looking at that post, I'd suggest the humfrz method - take the car into a shop and have them fix the AC.

:sigh:

Don't lie. You already had your mind made up before even reading the thread title.

This happened to me once when the car went in to limp mode due to disconnecting the OFT during operation. Cleared the fault code and AC returned. Maybe check for fault codes?

Pretty much so. For me, AC stuff is NOT a DIY thing. Not much anymore is a DIY thing - :sigh:
