With a 12v source, it definately clicks (clutch engaging), but doesn't seem to want to "stay" engaged. (when the engine is running, the clutch engages and rotates the compressor shaft 1/4-1/2 turn and then disengages)
I'm not sure where to check the air gap (or what the gap should be), but let me know and I'll do it.
I've jumpered both switches (one at a time) located at what I believe is the drier, and each made both front cooling fans kick on, but no change in the status of the clutch. I DIDN'T try jumpering them both at the same time).
I'm sure one of them is the pressure switch, but not sure exactly what the other one is/does.
Appreciate the help Larry - it's a convertible

, but it's also 98 degrees every freakin day here in Houston....
This is not cool.... LOL!!
Thanks!
