Finding the A/C clutch...
As Tegger suggested, you will likely want to look at a shop manual or sorts
for any detailed kind of answers. You may get lucky with: http://www.autozone.com/shopping/repairGuide.htm If I were to take my best guess though... I would trace the piping from the condenser (behind the rad) to the evaporator (should be an aluminum 'soup can' looking thing (might be encased in plastic with a site glass). Anyway, there should be a valve on the low side of this evap with 2 wires on the harness. If you jump these two wires, you should effectively jump power to the clutch. As for the dash switch, yes, I meant the in-dash AC/FAN or similar switch. The relay that controls the compressor usually feeds both from the low pressure switch and the dash switch. More aften than not, your problem will be found easily by checking both of these circuits. As for jumping the compressor clutch directly, I have never found any need as I always use the low pressure switch harness first. I would imagine it would be easy enough to do though to test the harness that comes off the clutch for +12V, GND and maybe a reference wire. Again, Tegger's advice to consult a schematic in a manual is very good advice indeed. There's no substitute for looking at the proper schematics. Good luck, Andrew. in article , Proctologically Violated©® at wrote on 6/5/07 1:06 AM: > Hey, shadetree's *are* the best! > > Shouldn't I be able to find wires at the clutch? > And where would I find the low pressure switch? > And by dash switch, you mean the on/off switch, right? > > I have found it pretty difficult to trace some circuits in cars.
