Hi Group!

I tried to find a guide for air self-diagnostic, but I could not find. My car Model is MB C-200 W203 -05.

The problem is that air-system blow warm air and when I turn both left and right AC/heater temperature controled low position then it begin to cool down.

so I would be interested if I can look this with self-diagnostic and see if there is some error code if that kind of self-diagnostic are available this model car?

Also if you have idea what's wrong pls. reply this.

thanks and regards, Kim

Im guessing that the car doesnt really have a problem.. Im thinking you should carefully read the hand book and follow the instructions therin, sometimes they can be difficult to follow...
