Since my wife bought the car from Hertz, the AC has never worked properly. It's just not very cold. She took it to Pepboys to have a leak test conducted and they told her (amongst a host of other things that needed replacing) there was zero pressure in the system and it required a new condenser and compressor.
Having purchased both new parts, I disassembled the front of the car and as I unhooked the pipe exiting the condenser (on the dryer side) there was a huge release of pressure and PAG oil which almost gave me a heart attack. Now I'm thinking there's no leak in the condenser as there's no sign of dye anywhere, and at just over three weeks since the test there's evidently still a lot of refrigerant in the system.
I've decided not to replace the parts, but go back to diagnostics and re-checking the basics. I've checked all the fuses and with the AC turned to 4 and the coolest setting, I can hear the compressor clutch click and kick in.
Can anybody suggest something I might be missing? I've read about jumping the pressure sensor, but surely if the compressor is kicking in this must be OK?
