I have a 1987 Cadillac Deville, this year there is not cool air and the (Service Airconditioner light is on and has been the last three years). I know I dont need Freon as I put my gauges on) The clutch on the compressor is not engaging when air is turned on. I am trying to norrow it down to the Switch, replay, or compressor (not sure where the replay is). Any advice would be appreciated. Jim Customer (name blocked for privacy)@gmail.com

Already Tried:
My Airconditioner stopped putting out cold air this year, it was converted to R134a in 1999 and has been cooling great ever since.
Checked Freon and pressor, oil. Checked Fuse 20amp tried new one. Need to find out where relay is and how to check voltage at compressor. or other options you might have.
