Do you have the correct High and Low pressures of the AC system-could be low on freon and its not kicking it, -start here

Apply power to the AC clutch and see what happens-possible low pressure switch and AC relay

Take it from the battery positive post straight to the clutch and see if it engages

I own a MErcury Sable and a Mercury Grand Marquis. My clutch on my A/C just went on my sable. If you dont replace it or set up a dummy pulley (or get a belt without a/c, it will burn your serpentine belt and it is unsafe. IF you go to a regular mechanicm, he should be able to get one from a junk yard and install it for 500-600 dollars
