93 CSET with no ac. Static pressure in system is about 100psi, holding steady. Relays are working, known by swapping them around. Computer seems to be relaying information about a/c "on" status, as the motor idle speed adjusts a little about 10 sec after ac is turned on. Compressor will run, and cool, with 12v jumped directly to clutch wire. Swapped in a known (pretty) good ACC, one that runs a compressor, anyway, and no ac. Jumpered across the contact wires for the frost switch. Nothing, nada, zip.
Also, what's that little switch on the compressor itself? Is that some sort of relay or sensor or something?
Any suggestions greatly appreciated!!
Thanks in advance,
Patrick
