Ok, this actually has to do with a 97 Chrysler Cirrus, but it's a basic AC question. I just replaced the AC compressor and charged it up. I hooked up a pressure guage to the low pressure hose and it is reading between 35 and 54, oscillating between the two every few seconds. Is it supposed to be a CONSTANT pressure or variable like it is doing? The guage says 22-44 is a good reading and anything higher will damage the AC compressor. Anyone know? -- Mike <font color=blue> At some point I'll be done building my truck and can actually go wheeling. Until then, I guess sex and alcohol will have to do.
