My is 2002 e320cdi. This morning I got air condition regassed. And I noticed while ot was being done that the compressor clutch isn't working - so I have no air condition she has manual air condition with knows. The EC button works, well the light cones on! I'm hoping it's not the compressor and hopefully just relay or switch, but where us the relay located? And is there any common faults I should be looking for. I've only had the car a month so unsure if wasn't working for long time, I just hoped it was low gas!
