It's a 2001 Ford ranger. Trucks been sitting most of the last year. A/C Clutch was not engaging. It has been low on r134 before. Added a can, or a partial can, of refrigerant. Now pressure surges upward when clutch engages, then goes down and starts cycling.
I stuck a forsale sign on it and put it out front. Weeks later, everybody wants it too cheap. I'm not giving it away for peanuts, so I might be stuck with it.
So I'm taking another look at the A/C. It cycles but there's no cooling. I'll have to dig into it again to give more detail. My foggy memory thinks cycling pressures were not so low as to indicate low refrigerant. It makes no sense to me that pressure increases when compressor starts. Would the surge in pressure on clutch engage be a sign it's full of air?
