Is there something wrong with the AC-Cadillac DeVille?

Is there something wrong with the AC-Cadillac DeVille?

Problem is, the compressor will only run a few seconds, then shut off. The indicated pressure in the system varies greatly as the compressor shuts off and on in very short cycles. I had cleared all the codes before attempting, but to no avail. Is there something wrong with the compressor, or am I just doing this the wrong way?

How can I tell if my Cadillac DeVille is low on refrigerant?

If the system is pulling in the refrigerant from the can, the compressor operates for a few seconds and then shuts down, check to see if the low refrigerant code is set (current). If it is, you may have a large leak in the system that needs to be repaired.

Why did my Cadillac DeVille compressor shut down?

So I got the message that I was low on refrigerant and the compressor was shutting down to protect itself. (98 DeVille) Thought I could handle the re-charge myself, but perhaps not!

Why is my AC not working in my GMC?

Please try again later. If you have a car made by GM such as Chevrolet, Cadillac, Buick, GMC, and Pontiac and your AC does not blow cold air and the A/C Compressor is not engaging it does not mean for sure that you have bad ac compressor or bad ac clutch coil, or low on freon, it also could be a bad ac pressure switch.
