Does anyone have a fuse diagram for the 95 S420? I have read that a fuse might be blown causing the left side of the car to blow cold air when I have told it to blow hot air????

The duovalve is sticking PN:A0018301484 or A1408300784 if your car has code 582 (air conditioner in the rear)

i don't believe in the lord! He's never bought me a Mercedes Benz.

I believe I read on this forum there was a way to push different buttons to get the codes you are referring to? Could you please tell me how to do so, and also where the part you are referring to would be located in the car. My estimation is that it is behind the dash located centrally and a little to the passenger side (if I read other posts correctly)

Sorry, this is my first mercedes and I absolutely love my car, just want it to work right.

I just bought this car last week. And, my hubby seems to recall having heat in all vents before we tried the air conditioning just to see if it works. What a bright idea in Idaho in winter
