A/C Issues..
 

Hey guys,

I am a long time lurker of this page but have never actually posted. I have an 08 tC and haven't had A/C for about 6 years now.
I finally have gotten the A/C to work at high RPMs but it is blowing warm air and overheating my car at idle. Here is what I have replaced in the last month....

Water Pump
Thermostat
A/C Expansion Valve
Receiver/Drier
Radiator (found leak where upper hose connected)
Radiator hoses (upper and lower)
Coolant temp sensor (2ish years ago)

I replaced the compressor and serpentine belt about 3 years ago because I thought that was my original issue. It ended up not fixing my A/C :(.
So I wouldn't think I need to change that again as it is only 3 years old. I can also hear both fans come on. I think it was the expansion valve that finally got it to at-least blow cold air at high RPMs.

Any advice would be greatly appreciated. Thanks!

Start by testting. What is the ac pressures? Low side and high side?

How do you test the pressure?
