1992 Suburban 2500, What is the easiest way to check the a/c compressor? When I turn it on I do not hear it engage. Thanks

Chances are the pressure switch is doing its job and the refrigerant charge is low. Dont run your A/C with the switch jumped out or you risk ruining the compressor.YThere should be a label near the emissions label telling what type and the amount of refrigerant you need. your auto parts store should have what you need to recharge your A/C. Good luck!
Also the schrader fitting is what the switch is threaded onto
