2001 AC Question
Compressor stopped engaging. When pressing on relay, it Engages. Blows Cold but is being overridden ( Not Correct ) .... Question is : what is not telling relay to cycle it on & Off ? ( I replaced the low side pressure switch, no Fix !)
Thanks for any advice ( I replaced the entire system last summer . Worked fine until Yesterday ? )

Have you jumpered the low-side pressure switch to see if the compressor stays clicked on?
If it does, then you have low refrigerant pressure. If there is no change (clicks off like it currently does), I would assume either the relay is bad or the fuse-box contacts may be bad?
