Question about 2003 Chrysler PT Cruiser
The two pressure sensors could be the cause. First check the pressure at the low pressure vale located in the left rear of the engine bay. At idle it should read around 35-50 PSI. The low pressure sensor is on the dryer, left rear of engine bay. It unscrews but has a valve that does not allow freon to escape. remove the electrical connection and jump the two wires and attempt to run the system, if it works replace the sensor. The high pressure sensor is on the end of the compressor (toward middle of car) and can be jumpered as well. I sugest that you only jump one sensor at a time. Good Luck

It most likely has a leak from an improperly installed o ring etc.
