General
1 On pre-1986 models the locks, with the exception of the one on the driver’s door, are actuated by solenoids (see illustration).

On 1986 models onwards, the locks are actuated by electric motors.

Switch (driver’s door lock) Removal
2 Raise the driver’s door lock fully.

3 Disconnect the battery.

4 Remove the door trim panel (Section 11).

5 Disconnect the wiring plugs inside the door cavity and release the wires from their clips.

7 Remove the lock from the door interior by guiding it round the glass guide channel.

8 Extract the two screws and remove the switch from the lock.

Refitting
9 Refitting is a reversal of removal, but before refitting the door trim panel check that the wires within the door cavity are out of the way of the window regulating mechanism and secured by strap clips.

19 Separate the solenoid from the lock after extracting the fixing screws.

Refitting
20 Refitting is a reversal of removal, bearing in mind the following points.

a) When fitting the door lock solenoids, locate the guide lock assembly into position, but do not fully tighten the retaining screws until after the bellcrank and rubber operating rod guides, and the internal lock operating lever are fitted.

b) Check that, when the solenoid is in the unlocked position, the gaiter has an uncompressed length of 20 mm (0.78 in).

c) Before refitting the door trim panel check that the wires within the door cavity are out of the way of the window regulating mechanism and secured by strap clips.

Rear door
Removal
21 Disconnect the battery.

22 Remove the door trim panel as described in Section 11.

23 Remove the bellcrank and operating lever by extracting the securing screws.
