Re: 1995 Cutlass Ciera AC
On the old pressure cycling switch of the old CCOT system, you could jumper out the switch to see if that was the problem.....you can't do that with the pressure switch.......
Have you checked hi/lo pressures with car off? should be close to ambient temp, for example, if it is 70 F outside on a cold engine, hi/lo = 70 psi......if much lower, you have a leak.....
Do you have access to a scan tool? Does it read the same a/c pressure as the gauges?
