The airconditiong in the my above vehicle has ceased to work. If I apply power to the clutch on the a/c unit it engages and cools perfectly. I have tried various suggestions from the Brickboard website,but still can't solve the problem. Any suggestions would be very much appreciated. Thanks. Kim

A relay , switch or wire is broken somewhere.
Is the pressostate on the filter/dryer cannister bad? It's a common failure, standard GM part you can pick up at any parts store and it has a schrader valve under it so you can replace it without opening the system.
Yes thanks for that James, I have actually unplugged that and bypassed it. Still no go.

I assume the fuses are all good? Is the thermal protector on the compressor open? Does it engage if you turn the defroster on?
Where can I find the a/c relay? It dosen't seem to be with the others behind the fuse panel [near ashtray] I do appreciate your time!! Kim
I have no idea unfortunately, your car is a generation newer than the pre-update 740s I'm familiar with, it might be listed in the owners manual though.
