226 Body

Remove the screws retaining the speaker to
the trim panel, withdraw the speaker slightly and
disconnect the wiring connector at the rear. Place the
speaker to one side clear of the work area.
On models with a step lamp located in the
door trim panel, remove the screws, withdraw the step
lamp and disconnect the wiring connector. Using a broad bladed screwdriver, carefully
lever the trim panel outwa rds and disengage all the
retaining clips. When all the clips have been disen-
gaged maneuver the trim panel from the door. Remove the screw retaining the speaker
water deflector to the inner door panel and withdraw
the water deflector.
Carefully remove the plastic sealing sheet from
the inner door panel.

Installation is a reversal of the removal procedure
with attention to the following points:

Ensure that the plastic sealing sheet is cor-
rectly installed and not torn or damaged.
Check the trim panel retaining clips and
renew any damaged clips as necessary. On models with manual windows, wind the
door glass to the closed position, install the
retaining
clip to the regulator handle and install the regulator
handle to correspond with the regulator handle on the
opposite door.
DOOR GLASS AND REGULATOR

To Remove and Install
Remove the interior trim panel and handles
as previously described. Lower the door glass to align the lift channel
with the lower aperture. Support the door glass and remove the
retaining screws from the lift channel and door glass. Tilt the door glass to disengage it from the
run channel, then lift the door glass out through the
door glass opening. Remove the retaining bolts securing the
regulator assembly to the door panel. On models with
power windows, disconnect the wiring connector.
Maneuver the regulator assembly from the door
through the lower aperture. Installation is a reversal of the removal procedure
with attention to the following points:

Ensure that the sliding surfaces are ade-
quately lubricated with a zinc oxide grease.
Loosely install the regulator assembly to the
inner door panel. Install the doo r glass through the door glass
opening, engage the door glass in the run channel and
loosely install the retaining screws.
Tighten the regulator retaining bolts and
operate the door glass a few times up and down to
ensure that the glass is centralized. Tighten the lift
channel screws and check the operation of the door
glass. Adjust as required.

Dismantled view of the manually operated front door

window regulator and glass components.
(5) Install the plastic sealing sheet, the trim panel
and the interior handles as previously described.

REMOTE CONTROL AND DOOR LOCK
To Remove and Install
Remove the interior handles, the trim panel
and the plastic sealing sheet as previously described.
Remove the screws retaining the door lock to
the door frame. Disconnect the operating links at the door
lock from the snipper button and the lock cylinder.
The remote control link can be left connected. On
models with central locking, disconnect the link from
the lock actuator.
Remove the screws securing the remote con-
trol to the inner door panel, release the link from the
inner door panel clip and w ithdraw the remote control
and door lock assembly from the door. Installation is a reversal of the removal procedure
with attention to the following points:

Ensure that the exterior handle operates
correctly and has 0.5-2.0 mm free play at the stepped
adjuster holder. Adjust the stepped adjuster holder if
necessary. Check the operation of the door lock assem-
bly before installing the plastic sealing sheet, the trim
panel and the interior handles as previously described.
