164 stuck heater direction flap
Hi everyone, thanks for looking at my thread. My 1990 164 3.0 V6 Lusso was off the road for 6 months and when I started using it again I couldn't change the heater air direction. It's stuck coming out of the dashboard vents. I press buttons, they light up and everything looks alright, but the air direction doesn't change. (NB. Heater temperature changes ok.) I cannot hear any clicking to indicate gear wheel problems, so I've been going with the idea it's electrical. Any suggestions greatly received and also any pointers as to where I might get a circuit diagram. Thanks again.
