Customer Question

A/C not working. Message on the display says, low refrigerant, compressor off,
JA: Have you checked the Freon level?
Customer: It is okay. This happens every so often and we reset the computer and it will work again. I have lost the codes to reset the computer and the compressor. Can you supply the codes to reset the computer to turn the compressor back on?
JA: What is the model/year of your Cadillac?
Customer: 1986 Eldorado
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Yes. If I had the codes I could fix it, but I lost my cheat sheet.
JA: Anything else you think the mechanic should know?
Customer: Everything else is fine.

Hi, my name is ***** ***** the freon level is good, then this is caused by a bad low pressure switch, and is very common on these, they are easy to replace, you just unscrew it from the a/c line and screw a new one on, have you done this yet?
