My rear aircon control is as you can see in the picture.
I´ve tried pushing left and right buttons with no results, stays like that.
Please, Any idea what is happening?
Thanks
Martin
On passenger cars "SYNC" would not block control from the rear or the front passengers, just makes all areas follow the driver settings until one of the other areas is tuned. A van could be different.
I did not check if this is on a lin bus, perhaps an issue there?
Fair enough. Yes it’s on a lin bus connected to main control unit - power and LIN (just considering a retrofit in W253 and it’s the same rear control unit on W447 and 205/253)
Cheers
