My 83 coupe a/c acts weird as well. The a/c works fine but when the heater is on max or whatever the a/c compressor turns on and off. When i put it on economy heat the a/c doesnt do that. Also heat only comes out of the floor and defrost which I know in the non electric g body ones the vacuum isnt working. Is that also the case with the electric ones? Im not used to these old style electric ones, i cant get it to do what i want. In my 2000 deville you put it on 78 degrees and it keeps it absolutely perfect temp in the car at all times you dont feel heat or cold coming on.
sorry to jack the thread, i got similar problems
