I have turned both controls to max and no compressor.  I think I'll put a
meter on the wire at the compressor and see if there is any voltage there.
I am pretty sure the problem is in a relay or fuse.  I'll  get out the
guages and jump the compressor clutch to see if the compressor is any good.
I am guessing the radiator fan should run when the A/C is on?  I'll have to
check and see if it does.  There might be a clue to the puzzle if it
doesn't run.

                                                   Thanks Ken,
                                                   Jay
