2004 GS430 AC not cold; no leak; compressor works
I'm trying to trouble-shoot the cause of this problem. I've already refilled the R134; checked with UV light at night and saw no leak; the compressor works. I'm going to check the ambient air sensor. Beyond these, what could the root cause be? Should I evac the system? Thanks in advance.

How do you know your compressor works? It kicks on ? If you recharged the system I would hook up a/c gauges and if your high side is not 150psi then it's a weak compressor. Just replaced mine same issue clutch would engage but no cold air.

Also if your low side is about 80 psi it's bad it should be 30psi or so mine read high side 100psi low side 70-80psi a good compressor should be 150psi high 30psi low with a/c on. (Ambient temp when I tested was 70 degrees)
