Me and trexturk(tom) both had the same issue with our A/C systems. Works great when the car is not heat soaked but once it gets hot, it stops working. Never figured it out on either car.
Interesting. See im pretty sure i recharged my system sometime last year. SO i wouldnt think thats an issue unless the shop didnt do it right. Which at this point they fucked so many things up previously i wouldnt be surprised.
