GF88.79-P-4003SX Outside mirror, component description
- up to model year 08


Design
The following components are installed in the left electrically adjustable and heated outside mirror (M21/1) and right electrically adjustable and heated outside mirror (M21/2):
^ Mirror up/down adjustment motor (M21/1m1, M21/2m1)
^ Mirror in/down adjustment motor (M21/1m2, M21/2m2)
^ Mirror fold-in motor (M21/1m3, M21/2m3)
^ Mirror heater (M21/1r1, M21/2r1)
^ Left outside mirror ambient lamp (M21/1e1)
^ Right outside mirror ambient lamp (M21/2e1)
^ Automatic dimming mirror (M21/1h)
(on model 221 with code (249) Automatic dimming inside rearview mirror and outside mirror (driver) and on model 216)
^ Left outside mirror turn signal lamp (E6/5)
^ Right outside mirror turn signal lamp (E6/6)

On model 221 with code (275) Memory package (driver seat, steering column, mirrors) and on model 216, the mirror adjustment motors are equipped with one potentiometer (M21/1r2, M21/1r3, M21/2r2, M21/2r3) each for sensing the position of the mirror lens. The mirror fold-in motors are integrated firmly in the frame of the corresponding mirror and cannot be replaced separately.
The mirror adjustment motors are combined as drive unit.
The mirror heater and the automatic dimming mirror are integrated directly into the mirror lens.

Automatic dimming mirror function
The mirror lens is electro-chromatically dimmable.This is realized by a layer of electrolyte gel in the mirror which controls, in increments, the light transmission, depending on the voltage applied.

Actuation
All components are actuated directly by the
^ Left front door control unit (N69/1) on model 221 or
Left door control unit (N69/1) on model 216 and
^ Right front door control unit (N69/2) on model 221 or
Right door control unit (N69/2) on model 216
