I'm having a problem with my A/C not working. It has a fresh 100% charge of refrigerant in the system with a professional machine, not one of those cans. There is a very slow leak somewhere, because more refrigerant had to be added a while back. It has since slowly stopped blowing cold air. I was hoping that a black light would reveal the dye put in the system to show the leak, but it has either washed away or could not be detected—I likely waited too long, or the leak can't be easily seen.

Seems now the main issue is that the A/C Compressor Clutch is not engaging—relay powered up, but there is no signal to relay to power up compressor clutch. It works if manually activated under the hood.

Can anyone make sense of these codes to point me in the right direction to rectify the situation?
MANY THANKS!!! & SAVE THE WAVE MY CORVETTE FRIENDS!!!

Update (if anyone is interested):

Air condition seems to work again at least. I guess I just have to bring it in at some point & have them diagnose everything, but I fear they will say it's gonna cost a arm & a leg once they get done resolving all these codes.

When you initially refilled the system, was your air working properly? If the system was properly refilled and clutch still wasn't engaging then the leak/actual pressures were not the reason for your inop condition.

You may want to be looking at pressure switch/climate module, the codes seem to indicate more of a wiring/communication issue than a direct A/C issue.

All of the B codes are related to your airbag, possibly has the sensors failing or grounds are failing/corroded (very common in east coast Vettes)
