Default 2003 Z06 A/C Problem, Please Help!

So, my a/c has been blowing hot air for a few weeks now, even at the coolest temperature. My coolant temp. is not over the normal, and when I used the a/c gauges (with engine running) both my hi and lo pressure were the same (@ ~120).

I noticed I threw the codes B0361 H and B0441 H for the actuators, but I do not think they are related in this issue. Thanks for any help!

looks like your high side is too low and your low side is too high... could possibly be the compressor... did you check the gauge readings with the ac running?... the compressor needs to be on to get a proper reading... do you hear the compressor turning on and off?

You may want a mod to move this to the TECH section

Whoops, sorry.

Anyways, the a/c was on full blast and lowest degree setting. The readings were read then and both were ~120psi. Thanks for any further help!

The first step I would take is make sure it is serviced correctly. I had the same problem and had it serviced. With a proper charge it cools just fine. I was down only .53 lbs but it would not cool. I have a 2001 and the correct charge is 1.75 lbs. The right way to service is to vaccumn down and recharge by weight with the correct amount of oil. The service facility should add dye to check for leaks.
