AC need help
01 ttq ac just stopped working last week. I have done several tests and I am now out of ideas. I have searched everywhere on the internet and haven't come up with anything that helps. Here's what I have done:
First I checked the system gas charge and it is normal so there is no leak.
I checked all fuses and all were good (#16 and the 3 under the hood)
I replaced the pressure sensor under the hood (thrust sensor). No change
Next, I checked the mag clutch which was not engaging. With the system on, the clutch is not getting any voltage and the ground was good. I then jumpered 12v in and the clutch engaged fine.
I ran the climate control diagnostics and with the system running the 20c (ac clutch voltage) is 13.6.
49c (fan temp) indicated that the fans are coming on at the correct temp settings.
Vag com scan reported no faults.
It has been in the 100s here for weeks and I am running out of patience with this. Any suggestions?

Evac the old coolant and add new. I'm sure you tried this but give it a shot.
I had done all the same when mine went warm went to Pep Boys he evacuated the old coolant and added new.
Colder than a witches T^$ right now...
