Rear Lamp Cluster / Central Locking System / Door Lock Motors
6.7.02 Rear Lamp Cluster Door Mounted Components
Procedure
1.
Remove the rear lamp cluster inner cover.
2.
Release the boot rear liner
3. Release the two nuts and one screw securing the
rear lamp surround and remove the surround.
Figure 7. Rear Lamp Cluster
4.
Disconnect the rear lamp cluster multi-plug.
5. Remove six nuts from the rear of the assembly and
lift out the lamp cluster.
Central Locking System
Description
Thecentral locking system consistsofmotoroperated lock
actuators in both doors, the boot and the fuel flap
mechanism. The central locking control module is located
inside the drivers side 'A' post.
Each motordriven lock actuator incorporatesa microswitch
which will signal a change of state when any motor runs
to drive the actuator. The microswitches are of the
changeover type and provide an earth for the lock or
unlock signals to the control unit.
The two door lock inputs to the control unit are connected
together so that operation of either door lock with the
ignition key will simultaneously operate the other door
lock. Similarly, the unlock inputs to the control unit are
also connected together for simultaneous operation.
The boot will remain locked or will be unlocked
simultaneously with the doors dependant on the boot lock
position.
With the boot key turned clockwise, the boot
lock operates in unison with the doors. With the boot key
turned anticlockwise, the boot lock cannot be unlocked
using the central locking system.
The boot can be opened at any time using the ignition key
irrespective of the central locking status.
6.7.03 Door Central Locking Motors
Procedure
1.
Remove the door inner panel.
2.
Disconnect two plugs on the central locking motor
unit and one plug on the door closed switch.
3. Release the interior door catch operating rod from
its guide clips and detach it from the lock
mechanism.
4.
Disconnect the outer lock operating rod.
5. Remove three lock securing screws from the door
rear edge.
6. Remove the motor and lock through the access
hole.
7. Remove the motor securing screws and remove the
motor from the lock assembly.

Electric Windows - Fault Analysis / Window Motor Removal
[n:m3^^
Electric Windows
Description
Power to the window wind circuits is available
when the ignition switch is on and is supplied
through a thermal cut-out to the left and right
window switches. The switches are double pole
plus earth so that the current through a window
motor may be switched in either direction to raise
or lower the window.
DB7 uses frameless door windows which seal
against rubber strips around the body shell door
opening.
To avoid damaging these seals during
door opening, the door glass must be lowered
before the door can be opened. This function is
controlled by the window control units. The units
are mounted on the inside of each door frame and
will sense if a door handle is pulled to open the
door. Before releasing the door lock, the control
unit will drive the window wind motor briefly to
lower the door window glass down until it clears
the window seals. Similarly, after closing a door,
the window motor will be run to raise the door glass
to seat the glass against the body seals.
Fault Analysis Procedure
a) If a window fails to operate, check for fuse failure
and the connectors for poor or open contacts.
b) Check the thermal cut-out by shorting across it and
operating either window. If the windows operate
with the short
ci rcu
it but not without, the cut-out is
faulty.
c) With the ignition on, battery voltage should be
available between the inputterminalsof the switches
and chassis. Operate each switch and ensure that
battery voltage is available between the switch
output terminals and chassis.
d) Measure voltagefrom each switch inputterminalto
the switch earth return terminal. If no voltage is
measured,
the earth return line is open circuit.
e) Measure continuity through the wiring from the
switches to each motor. If continuity is correct,
remove the motor for bench testing.
6.7.04 Door Window Motor
Procedure
1.
Remove the door trim panel and the glass inner
sealing
trim.
Figure!. Window Securing Screws
2. Position the window to gain access to the slider
bracket and glass securing screws.
3. Disconnect the battery earth
lead.
4.
Remove two screws securing the glass to each of
the two slider brackets. Loosen the two screws
securing the glass to the elevator
rail.
6. Slide the elevator rail forwards until the glass
securing screws are opposite the wide opening of
the rail keyhole slots and remove the glass from the
top of the door.
7. Disconnect the window motor multiplug.
