Question about 1988 Cadillac Sedan DeVille
Depending on if you have a late in the year production model or early there are 2 wiring diagrams for this year and they had 2 A/C COMPRESSOR CONTROL CIRCUITS. It almost sounds like you are having an issue that is causing the body control module to shut it down.I can send you the wiring diagrams for both types that I have found. Please let me know if it helps or if I can help more but I am sure I am going in the right direction on this if compressor is good and you have proper freon charge.
Im pretty sure you cant bypass that switch there is another switch kicking this on and I would almost bet it is a high or low pressure switch it could be a relay but without testing these components its hard top pin point. These wiring diagrams would help
