Can anyone tell me where the relay(s) are located on a 2003 C230 Kompresser. The AC Compressor will turn on and work fine when we give it current but it will not go on when switched on. So we're thinking relay, swicth or both


You are right. It might possible be an issue with the relay.


To located the AC relay in your 2003 C230 Kompressor, Have you looked at the fuse/delay diagrams in your car? Mostly on the left side of the dashboard?

That should  be able to give you a good idea
