Hello I will help you with your question,
I can help you test this if you can catch it while it is not working.
See if installing a paperclip in place of the low pressure switch on top of the accumulator near the firewall starts it up again. I have replace a lot of low pressure switches on these. It just screws on and off, no pressure is lost. Accumulator is the large silver can
Let me know if that is it.
Thank you

Good, reconnect the low pressure switch and pull the AC relay from the underhood fuse block and see if it is marked with 1,2,3,5 by the pins or on the side. Use a heavy paperclip to connect the #3 and the #5 pin socket and let me know if the compressor runs and if the system is cold.
