I am having an issue with my w210. On a couple of occasions I have had my AC refuse to cool. The situation only lasts a few minutes and then cools great! Today, the other extreme..I tried to turn the heat on..and it wouldn't heat. I turned the climate control to 80 and it was blowing 52degree air. If I pressed the EC botton it would only send outdoor air in the car.

Is this a duo valve(?) problem?
Thanks!
