| A quick update - it's not the fuse. Fuse #5 in the box covers the entire aircon system and various other circuits as well, and it's good. And there's power to the switch in the dash, because the little red light illuminates when I switch the a/c on.
I'm ready to check and/or substitute the relay, once it's clear where I find it...
As for testing the clutch itself, i'm confused. If you apply 12v power direct to the clutch terminals, but the refrigerant is low, will the clutch engage? And/or will such a test do any damage if the freon is indeed low?
And by the way, my concern about R134a is not its absolute cooling efficiency, but the headache and expense of changing all the tubes, seals, drier, etc etc etc.
