ac problem.

[twistedclown024]

Hello I have a 2000 Pontiac sunfire the ac is not working. Start the car up press the ac button turn on the blower it all comes on but never gets cold. Did some looking and the compressor is not kicking in. Well I checked the compressor it is in good working shape. I took a battery and hooked it to the compressor and it does lock in and out. So I checked the wiring to the Compressor and its dead no voltage. Looked at the fuses all good relay good I know the PCM controls it so I checked the fuse for it good. Replaced the pressure switch on the ac line still nothing any idea.

It is probably low on freon. The comp. will not kick in if the psi is too low.
