Heres an interesting one. My lovely (UK: Right hand drive estate) 2011 C220 S204 has decided to chill the driver whilst keeping the passenger cosy warm. It's not the Air con. No error messages on dash or through the Diagnostics reader (icarsoft).
The chill feels like external air. I'm thinking blend flaps but here's the puzzle: the rear passenger compartment vents (the ones at the back of the armrest) ALSO have warm air out of the left vent and cold air out of the right vent. (a puzzle because I thought the rear passenger compartment was not able to have left and right temparature adjustment.)
If I press the recirculator button the drivers side windscreen foggs up quickly.
Air con clears the screen and does its usual thing on both sides.
Of course no amount of turning up the heat (on either side) has any effect on the drivers side. Seat heater works fine though Thank God!
(Other things I think are irrelevant but perhaps should be taken into account: Comand screen is blank, functions (except sat nav of course) work fine. I had a leak of a litre of w/washer fluid in the rhs passenger footwell GRR. The car has done 165Kmiles)
