OK, so my 2011 e350 has been sitting at the airport for the last week. When I arrive today, I get it, start it up without issue, and go to click the AC on. I notice there are no lights coming on the control unit and AC is not blowing - I click through and no heat, nothing. I also hear the cooling fan running, even though I just started the car. So I shut it off and restart, and the same thing: no climate control lights, AC or heat and the colling fan is continually running?

Looked at the fuses, seemed ok but I don't know which one is the correct fuse for climate control.

Anyone have an clues? Fuse, Relay?

Thanks!

Ok, so I ran a code check...no codes. Pulled the fuse to check and it was ok. Started the car and everything was working again.

Fuse pull reset? Fuse Dirty?

Who knows....

Thanks konigstiger! BTW..we visit Scottsdale a lot!
