The motor and its carrier has been fitted upside down...easily done, get them to correct itMercedes broke my wing-mirror during a service(!) and have fitted a new one...
BUT the electric controls seem to be reversed! Am i right in saying that up is UP, and down is DOWN on BOTH mirrors? I can't remember, but i'm sure it was!
on the mirror they've changed if I press the control up, the mirror does the opposite!!
PS Mercedes garages here in the UK seem to be run by monkeys!
