    Object Number: 284162  Size: MH
  1. Snap the actuator shafts into the power drive unit (8).
  2. Connect the electrical connectors.
  3. Rotate the actuator shafts in order to align the ears with the corresponding slots in the back side of the mirror face (7).
  4. Align the swivel (3) on the power drive unit (8) to the pivot points on the mirror backing plate.

    5.3. Tilt the mirror (7) toward the outside actuator shaft (4).

    Apply pressure on the block until the ratchet sound stops.

  8. Inspect the mirror for proper operation.
  9. If the mirror is not operating properly, inspect the actuator shaft alignments again.
