Hello from Chicago
Berlina is a 95 S420 and she is a bit under the weather. The temp control lights flash on to off, move from F to C, and end up on defroster. I'm unable to turn off the controls until the car is turned off. I have replaced the regulator underneath the cabin filter, but did not fix the problem. The flappers also clack shortly after starting the car. Any help or reference to were I should post issue?
Does this sound like a vac control unit?
