To remove a manual mirror, you have to pull off the control knob from the adjustment handle, unclip and remove the inner trim panel from the door, and undo the retaining bolts to remove the mirror. Recover the insulation between door and mirror, changing it if damaged and refit by reversing the removal procedure tightening the bolts to the specified force. For an electric mirror, starting with the removal of the door inner trim panel, unplug the mirror wiring connector, unscrew the holding bolts and remove the mirror, recover the insulation and renew if necessary, refit in reverse order with the correct torque. When dealing with the mirror glass, try to tilt it all the way in, use a screwdriver to loosen the holding clips and carefully remove the glass, being careful not to break it and wear gloves for safety. Upon refitting, reconnect any wiring and clip the glass back onto the motor/adjuster, putting force only on the middle to reduce the risk of breakage. For the electric motor of the mirror, first remove the glass, then unscrew the holding screws to remove the motor assembly while unscrewing the wiring as it is exposed, and when fitting it back in, firmly reconnect the wiring, seat the motor, screw it in place and replace the glass.
