1995 E320's AC has quit working I pulled out the climate control relay behind the battery to give it a look. I then jumped the two prongs that basically straight wires the compressor and plugged it back in. The compressor came on just like it should, so I thought that my relay had just went bad. I ordered one from Mercedes and installed it and I still have nothing. With the new relay if I just barely sit it down on the connector it will engage the compressor for just a second then disengage. When you plug the new one all the way in it does nothing. I know I have the right amount of freon in the system because I checked it when I had jumped the old relay. I don't know what else to do I don't want to leave the compressor straight wired because it will run all the time. Does anyone have any ideas to what my problem may be?
