hiya buddy, yes left mirror works fine
OK, well the mirror pivots on a half sphere shaped housing. Within that there are three motors at 120 degree spacing from each other. The three motors operate together to allow movement in every direction. sound like one has died.
If you remove the glass you can see the housing. It is held in with a screw in the middle from memory (obvious once you look at it).
Easy enough to pull it and fit a replacement.
Or you could simply swap the whole mirror. Easy to change your coloured casing over.
