car is a E220 coupe. Some idiot has just hit my drivers side mirror and smashed the glass and put the whole thing out of kilter, i can adjust up only to a certain limit but this is not enough to see back i.e. the whole thing is pointing about three notches down, is there a simple way of adjusting the electric mechanism by taking it apart without having to replace the whole thing at vast cost, I cannot find any screws to undo or a simple way of of undoing the damn thing
