Hello, I'm new to posting on fourms. I have a 05 Tahoe with automatic A/C. It's a 2 wheel drive 5.3L and the rear A/C cools great the front is not at all.
I have replaced the EVAP coil in the dash (due to it was leaking)
Orifice tube, low pressure switch, accumulator and I also tried a A/C Controller out of my other 05 Tahoe to eliminate that as a problem.
I've went through all 4 blend door actuators and confirmed they are working correctly (I also tried DEFROST and it dose not blow cool air either)
The refrigerant line coming from the compresor that has a y and splits to the back ( is ice cold) and to the front accumulator ( is the same temperature as the engine compartment). Also the accumulator is warm as well. The low side line to the inlet side of the EVAP coil is Ice cold. I have removed this line with the y and inspected for any sign of blockage, but it is clean as a whistle.
I have vacuumed the system for 2 hours and let it stand for 2 hours. There is no longer a leak.
I charged the system with 2.5 LBS of R-134A
What do you guys think?
