The last two times I've driven my 2010 e350 the climate control system has gone bonkers. For some reason the fan comes on full blast and the controls do nothing to turn it off. None of the controls do anything. It just blasts air. It even keeps going after the car is turned off. After a few minutes it stops. I can then restart the car...and for a while it works fine. Then the same thing happens. Full Fan, inoperable controls.

Any thoughts? Hopefully a simple fix.

Had the exact same issue! Happened at 4000 miles on my 2012. Dealer replaced the control module.

I remember a TSB about bad fans in this thread:
