Help!!! Need AC electrical diagram
I had my car in the shop today for what I assumed was to top of the A/C as it was not blowing real cold at idle.
My mechanic says the refrigerant level is fine.
He said the electric fan is not kicking on with the A/C as it should thus causing the compressor to over pressure and shut off. It works fine when I am moving because (I think) the air flow is enough to keep everything happy. He thinks the relay is bad as the fans come on when the car gets hot.
I need an electrical diagram to hunt the problem down without just randomly replacing parts. Can anybody help me out? 94' E420. Mechanic does mot have MB electrical info as he does not work on them (except mine!!).
