87chevy.com is right! If you're not careful, you can spend a pile of money throwing parts at it and still not resolve the issue. One of the major keys in properly diagnosing an a/c problem is know what the high and low side pressures are with the system operating at idle and at 1500 rpm. Head pressures can tell you a lot of information about what is going on inside the system. If you have a set of gauges and can get those readings, maybe I can help.
