Door Locks: Service and Repair

Replacing door lock mechanism




1. Close the window. Remove the locking knob, interior door trim and moisture barrier. Service and Repair
2. Manually rotate the latch mechanism on the door jamb to the latched (closed) position and remove the three retaining screws on the door edge.

NOTE: If the screws are frozen they can be removed with an impact driver.

3. Working inside the door, remove the link rods from the inside door handle, the lock cylinder, and the central lock motor.

CAUTION!
^ When removing the link rods from plastic parts do not stress the plastic as it will break.
^ Do not bend or distort the link rods. The latch mechanism will not work property when the bent links are reinstalled.

NOTE: The central lock motor can be removed to gain more working space inside the door. Service and Repair

4. Loosen, but do not remove, the screws for the outer door handle as described above.

NOTE: Loosening the outer door handle screws will allow some clearance for the latch mechanism to be removed. The outer door handle can be completely removed if necessary.

5. Carefully work the latch mechanism free and remove it from the door.

Installation is the reverse of removal. Apply a thin film of chassis grease (Saab special chassis grease - ESSO Nebula EP2 or equivalent) to the latch mechanism. Test all the latch functions before installing the interior trim panel.
