Electric folding mirror fault c200 Coupe 2006 model Benze

I have a C200k cdi coupe with electric folding mirrors but they have stopped working correctly so looking for some advise! The indicator on the passenger side has stopped working also and displays as an error on the dash, i have taken the mirror casing off and put it on drivers side connection to check it and the led's worked fine on that side so nothing wrong with them, nor are there any splits in the wire for the indicator on the passenger side so am at a loss as to why this is happening... is there a fuse anywhere? Also the mirrors are folding in electrically but not out, if you push them back out they stay there, then if you press either fold-in or fold-out button they will fold in, but never fold out electrically... can't be a problem with the fold-out button on the dash as pressing it does do something... just not what it should... ie folds them in and not out! Has anyone got any ideas how i can fix this and avoid taking it to the stealer
