Default Why does the A/C on my 2004 Toyota Camry only blows cold at high rpm?
I had the compressor, AC receiver drier, condenser, all o-rings replaced and had the system recharged. The clutch seems to be working as it should. The only part I have that was not installed was the expansion valve. At an idle the a/c air is slightly cooler than the outside temp (and I am in southern cal.). I have to be on the freeway for the system to perform as I think it should. Any Ideas?

It sounds to me like your cooling fans are not turning on when the A/C kicks in. When the car is stationary with A/C running, those fans behind your radiator should be going full blast to pull heat off the coils. If not, the A/C will only be able to cool the air slightly, if at all. To check, put car in park and idle with A/C running. Pop the hood and check to see if the fans are running full blast. You should feel a lot of hot air being blown around the engine. If you don't, then that is the issue. If the fans are running as they should, then the issue is beyond my expertise.
