Customer Question

Hi Mr. Jerry, I have a 1999 Cadillac Sedan Deville, A/C problem. A year ago i saw your web conversation with another and learned about the A/C codes. I followed your instructions after and helped me fix it. I was getting the "Low Refrigerant \ A/C off" message. Anyway all was good until recntly I got the same message and went thru the same procedure and now after putting in 3 cans of 134A it works then stops and it sounds like when I TURN THE A/C ON the compressor kick on and off every 3 secs?

It only kicks on/off when I turn the A/C on. Is there to much pressure in the system?

Hello, the refrigerant capacity is 32 ounces, how many ounces were the cans you used? Do you have any way to check the low or high side pressure?
