Is the compressor running? If it is it's not pumping. It's broke.

What are the pressures? Did you charge the system amount back into a deep vacuum?? Your car uses a variable displacement compressor, and the control valves do go bad, if your O tube was black, or even partially clogged, it's a good bet the compressor is shot. Most likely cause, poor retrofit in the past..Let us know the pressures and the answer to the vacuum/charge question and we can help you...

You have a V5 compressor. Several different things could be going on.

Check to see that the center hub of the clutch is actually pulling in, and turning the compressor shaft.

If the compressor is turning, record the high & low side pressures - and post them.
