I have an 02 Stratus with the 2.4L 4 cyclinder. The air conditioning works when the car is first started. The air runs cold for a few minutes then when the compresser turns off the air starts getting warm. I have made sure that there is the proper ammount of refrigerant. I have also taken out the relay and jumped it to make the compressor turn on, but the relay itself is good. The bottom line is the air only runs cold when the compressor is turning. I am out of ideas. Does anyone have an idea of what might be going on with it?
