There are troubleshooting procedures in the FSM (link in sig).
i see, so if it thinks the pressure is too high should i release some of it? i'm about to pop the hood and see if any wires are cut/ pinched

Not at this point. I'm just making a guess based on my previous experiences with car A/C. See if the FSM or another forum member can help you find the root problem before you start "fixing" things.

Checking the wiring is a good idea. The FSM will have wiring diagrams, wire colors, etc.

SouthArk370Z meant that the problem might be the pressure switch itself regardless the pressure of refrigerant in the system.
SouthArk370Z and Ghostvette like this.
