ccgoodwrench Posted August 18, 2007 Report Share Posted August 18, 2007 Do you have e-fans? (didn't see it in your sig). If you do you have to wire in a relay to kick one of the fans on to get air across the condensor, the noise you are prolably hearing is the AC building up pressure. One day I hook up a set of AC gauges and the high side of the system was reading about 420 PSI, I hook up the fan to run when the compresor engages and now the pressure is back down to 200 PSI. I hope this helps. Quote Link to comment Share on other sites More sharing options...

Cost me around $1100.00. Contact Zippy. He can get you a deal on the compressor if you have someone to install it or can do it yourself.
