Before you put 12v + to the compressor how many oz's did you charge the system with?Also do you have climate control or manual a/c let me know.

It hold's 36oz's I emailed you the a/c spec's to your personal email.I would hook up some pressure gauge's and see if the pressure's are within range for the pressure switch to kick the compressor on. Or turn the compressor off. Let me know what you find I think you can rent the gauge's from auto zone.
