from memory
open door this allows access to 2 hex screws in the black cover you can see from the inside when shut, you can then see 3 Phillips screws holding in the mirror itself
detach power wires
cant remember if the door card needs to come off for access to some hidden screw if not its in your hands then.................. this then allows you to see under the unit where there is access panel and then you can see the innards of the unit itself, believe it or not its not usually the 3 Phillips screws that need tightening but the casing itself that needs tightening to the mounting point, its about 2 out of 10 on the easiness scale
