3.

To adjust the alignment of the top edge of the glass, it is necessary to adjust the height of the reaction
channel.  Remove the window winder handle and door trim panel, slacken the reaction channel fixings,
and move the channel up or down as required.  Raising the channel will raise the rear edge of the glass.

4.

To adjust the fully up position of the glass, the eccentric stop on the toothed sector of the winder mecha-
nism must be rotated as necessary.  A mesh friction washer is fitted between the eccentric and the sector
to help retain adjustment.

To replace the door window glass
1.

Remove the window winder handle, and the door trim panel.

2.

Release the three fixings securing the slider channel to the bottom of the glass.

3.

Do not attempt to withdraw the glass from the door without first removing the door waist seal.  Carefully
prise the one-piece seal off the door shell inner and outer flanges, and release the push fixing from the
seal moulding at the rear end of the door.  Withdraw the glass from the door shell.

4.

Note that new door glasses are supplied complete with jig bonded Nylon sliders and stud plate.

5.

Fit the new glass into the door and re-assemble in reverse order to the above.

6.

Adjust the glass position as detailed above.

To replace door winder mechanism
1.

Remove the window winder handle, and the door trim panel.

2.

Release the interior release control rod from the door handle and unclip from the latch mechanism.

3.

 Secure the door glass in the fully raised position, and release the three fixings securing the winder
mechanism to the door;
-

two fixings adjacent to the winder spindle;

-

on fixing through the static pivot of the primary scissor arm

4.

Manoeuvre the mechanism to free the winder spindle from the door, and to disengage the two upper
sliding bosses of the scissor arms from the window channel, and the lower sliding boss from the static
reaction channel.  Withdraw the mechanism from the door.

5.

Before fitting a lift mechanism, lubricate the three slider bosses and the sector teeth with Century Luplex
M2 grease (or similar).  Fit the mechasnism into the door and engage the three slider bosses in their lift
and reaction channels before securing with the three fixing screws.  Note that a single M6 spacer washer
is used between the pivot of the primary scissor arm and the door shell.

Door glass guide rails

Two guide rails are used for door glass; one for the front and one for the rear edge.  Each of the steel,

black zinc plated, guide rails, is secured by a single screw at the top end to a jig bonded bracket in the door
shell, and by a threaded adjuster at the lower end, engaging in a threaded block fixed to the door shell.
Screwing the adjusters in or out will set the inward tilt of the glass and the contact between glass and door
weatherseal.

To remove a guide rail, first remove the door glass (see above), before releasing the single screw at the

top, and releasing the threaded block from the door shell.

BR.12 - ELECTRIC WINDOWS 

(Parts List 11.02)

On cars so equipped, switches for the electric windows are mounted in the front of the door trim panels,

and are operative only with the ignition switched on.  To help locate the switches in the dark, an illuminated dot
is provided in the ‘down’ button which glows amber when the lights are switched on.

To lower a window, switch on the ignition and press the lower, dished end of the switch in the relevent

door.  Release the switch to stop window movement.  To raise a window, press the upper, domed end of the
switch.

The electric operation of the door windows comprises;

-

An electric motor and winder drum assembly mounted on a bracket which is bolted to the door shell.

-

A guide channel for the window lift block, incorporating top and bottom cable pulleys, bolted to the door
shell.

-

A single drive cable running from the window lift block, around a guide channel pulley, through a flexible
conduit, around the motor driven winder drum, through another conduit, around the second guide channel
pulley and back to the window lift block.

-

An adaptor plate bolted to the stud plate on the lower edge of the door glass.

Door Glass Adjustment
-

The door glass guide channels and adjustment procedures are the same as used on manually operated
windows.  Refer to sub-section BR.11.

-

The upstop for the door glass is fitted at the top end of the lift block guide channel in the form of an
adjustable stop screw against which a projection on the window lift bracket abuts.

-

The front/rear height of the top edge of the glass may be adjusted at the slot where the front of the window
lift bracket attaches to the door glass.

Replacement of Window Lift Mechanism

The window lift mechanism comprises the motor, drive cable and guide channel assembly as a complete

unit.  To remove the mechanism:
1.

If possible, raise the window fully for optimum access.

2.

Remove the door trim panel and disconnect the window switch.  Peel off the plastic water shielding.

3.

Release the window lift bracket from the door glass and secure the glass in the fully raised position taking
care not to damage the door waist seals in the top of the door shell.

4.

Unplug the motor electrical connector.  Release the three fixings securing the motor mounting bracket,
and the two remaining fixings securing the guide channel to the door shell.

5.

Carefully manoeuvre the lift mechanism from the door.

6.

Refit in reverse order to removal, noting that the motor mounting bracket is fixed directly against the door
shell, but that 4mm plastic spacers are used at each of the three guide rail fixings..
