Outside rear view mirror assembly (1987-1989).
Outside Rear View Mirrors

The remote controlled outside mirrors are electrically heated. The mirror glass, mirror drive motor and mirror housing are available separately from an authorized Porsche dealer. Note that two variants of the outside power mirror was used in the Carrera series: The early variant was used on 1984 - 1986 cars and the later style (as shown) was used on 1987 - 1989 cars.


  • The main difference between the early style mirror and the later style mirror is the way the glass is mounted to the motor assembly. On 1983-1986 cars, the glass is retained by pins at all four corners. On 1987 and later cars, the glass is retained by a circular locking ring. The procedures given are for the 1987 - 1989 mirror assembly, the early assembly is similar.
  • Mirror heating is controlled by the rear window heater circuit. See 970 Electrical Wiring Diagrams.
