My 2001 PT has just started a strange thing a week or so ago. When I start the car and it is at idle and turn on the A/C the system seems to cycle the compressor on for a few seconds. No more than ten. Then it is off for about 30 seconds and cycles on for several seconds and then off again. The air is obviously not cool. Now, when I start to drive off the system works perfectly. Not only that, but it will cycle and cool correctly while at idle and also work perfectly if turned off for an hour or two and when started and at idle it will cycle and cool correctly. This is a problem because when I transport my mother who is partially paralyzed from a stroke, I need to set her in the car and then either place her regular wheelchair in the back or if she uses her power chair I have to pull the ramp out and load the chair in the back and restow the ramp. Living in Florida necessitates having the A/C running for her while waiting. Stepping on the accelerator and racing the engine has no effect. The Freon level is fine and the wiring is fine. There are no fault codes and I and the repair shop are at a loss. I can't leave the vehicle there overnight so they can see the problem. I am disabled myself and with the dealership so far away, I can't ride with just the windows open in 97 degree weather with sporadic rainfall and high humidity.
Sorry for the long story, but I wanted to explain reasons for not letting the situation start where the repair shop or dealer can see it for themselves. The car is a limited edition with 43000 miles on it. I know we don't drive many miles. This problem seems to occur after sitting overnight. Last week it was driven three days in a row and each morning it was the same problem.
Thanks
