I have a 2001 Dodge Intrepid SE 2.7 V-6. I recently charged my AC and after a few problems, the AC blew cold for a few weeks up to today, Today I turned the AC on, it worked fine, when I got to to a stop light I turned it off, a few minutes later, turned it back on, nothing happened. Check the AC compressor, getting no pressure when car is on, but when it's off I get a static pressure reading, the clutch is engaging, I made sure of it, after checking all the fuses and relays, the clutch is engaging, but the compressor I'm not sure if its running. It did this to my last time, I couldn't get a running pressure measure, but I could get static pressure readings, what should be my next move be? I don't want to try charge it, it won't do any good until I know if the compressor is seized or not, could the drive belt be causing any problems?
