I have a 1995 Dodge Caravan with A/C problems. I recharged the A/C unit with R134A. The pressure reads 60 when the Compressor is off and less than 20 when on on the low pressure side. It is Cycling with 3 seconds on and 1-2 seconds off. There is no cold air comming out. If I shut off the vehicle, the pressure hangs around 55-60. I have not detected any leaks. Any help would be appreciated.
Thanks Joe
