Not the SRT, but the AC systems are similar/identical...
Last year I had to replace the cam seals due to a MASSIVE leak they were allowing, due to a prior shop installing no-name seals (during a timing belt/water pump scheduled replacement) that failed after only 20k miles.
That job was done successfully, by me, but now after the AC system was recharged (pulled down so I could remove the lines to do the aformentioned seals more easily) the AC system won't turn on.
I own an Autel MaxiSys 906Pro, and I can go in and manually engage the compressor (I don't run it for long, for fear of causing an overpressure condition.)
I've tested the fans, compressor, refrigerant pressure (using gauges), control states, command requests, anything I can think of and can test/control with the tool.
When I do turn the compressor on, the high pressure line gets cold, the cabin gets chilled air, but I can't activate the system from the controls.
You can see that, the Pressure Voltage is stuck at 5v, and the Pressure value is stuck at 580 psi, but I can't for the life of me find that sensor on the car, or in the OEM service & repair manual, which I have a copy For the snapshot above, the tool is commanding the compressor on, the blower is on high, and the AC button is pressed (light is on.) Again I've tested comms on the car and the CGM is seeing the button being pressed, but it won't command the compressor to turn on, due to I suspect the pressure reading being sky high. The only item of question on this car, is the high pressure switch
on the compressor itself looks a little suspect, in that it has a chip out of the green part of the plastic body of it. I thought that was only a switch though, since it's a 2-wire connection. Every other chrylser I own has a 3-wire sensor connected to the high side line coming out of the compressor, except for this PT cruiser.
If anyone has any thoughts on this I'd appreciate it.
