Hi there, my e320 1997 w210 model climate control is playing up. the fan works correctly on the 1st 3 speeds then the 3 after that it stays as if it were still at no.3. The climate control has always had no leds that work on it ie when you press heated screen the fan switches to max and blows at the screen but the red led in the switch doesn't light up. Same for when you press auto, charcoal filter and so on. The Rest button has also never worked which gives me the problem of not being able to perform the self diagnostic. I'm thinking it could be the rectifyer?? When auto is pressed it feels like it still only blowing at speed 3. Is the rectifyer the same on the models without digital climate and where abouts is it situated. Would anyone have a wiring diagram showing how to test the rectifyer?? Any help much appreciated.
