Re: 99 Venture, AC Not Cool

OK, with the engine off the pressures on both sides read about 75-80 psi. According to the manual over 50 psi is good. With the AC on full (blowing not cold air) the low side reads anywhere from 60 to 80 psi and the high side from 100 to 130 psi this is dependent on engine RPM from idle to about 2000 RPM. The compressor turns on but is making a really bad clicking sound. I'm guessing the compressor has gone kap-put. I can't complain since my wife hasn't let the compressor rest for the last 8 years, hot or cold, rain or shine, winter or summer.

Has anyone changed one of these out on this car. According to the manual the electric fans have to come off the radiator then you basically unbolt the compressor and remove and of course with upper front engine mounts, drive belt and assorted electrical connections.

I am familiar with AC work so I know enough to feel comfortable with doing it myself, my only fear is that this is a Venture van and nothing is easy to get at as it seems.
