I want AC but can't get the compressor to engage. Any thoughts AC is black magic to me. The test that my service CD told me to perform indicated that the kilma relay was bad. So since it is getting hot I spent $130 on that, needless to say it didn't do anything. So the car is a 1987 300SDL that was converted to R134 by a pretty good dealer in 1995. The kilma relay is new, but the compressor still will not engage. Any ideas?
