There should be power flowing thru the switch with the A/C engaged. The sw is screwed into the side of the rec drier. There is a connecter near the drier , it will be easier to check for power there
: : Was there already a charge of freon in the system ? Is the compressor getting 12 volts when there is freon in the system ? The compressor will not power up with little or no freon in the system, You may have something as simple as a fuse blown. Does the aux fan come on when you push the snow flake A/C button inside ? .If there is no power getting to the compressor, but the fuse is good, the pressure sw on the rec drier could be defective or just plain disconnected. Take a small screwdriver and with no EPD or EPA squads around, just barely push in on one of the scrader valves of the A/C , any freon escape ?

:
: The Aux. fan does engage when the snowflake button is pushed and the fuse was not blown. My similar experiences with other cars though minimal would dictate low freon but this seems to be more involved. Getting to the compressor leads might be tricky and how do you trouble shoot the pressure switch? Thanks for your help.
