Tail gate wiper/window problem

raj3930 · Oct 2, 2006

Hi all
New to this forum and Freelander owning.Having read some of the posts I suspect I will be asking for advice quite often .
As a first request for help then.... the tail gate wiper has packed up (whilst using the washer) and the tail gate window stopped working on the switch at the same time. It does drop and raise when opening/closing the tail gate though.
Grateful for any advice.

you need a new wiper motor, whats happened is.......because the wiper motor has packed up, the ccu (central control unit) doesn't know the position of the wiper, therefore it thinks the wiper is not parked and so will stop the tail window from working

O.k. Thanks for the help. Much appreciated

Rear
Wiper
The rear wiper is switched on and off by pressing the switch mounted on the RH side of the
instrument pack. The rear wiper is controlled by the Central Control Unit (CCU) and will only
operate when the ignition switch is in the 'ignition' position.
NOTE: Rear wiper operation will NOT be suspended while the engine is cranking.
The rear wiper will stop operating and return to its park position if any of the following occur:
The tail door is opened.
The tail door window is opened.
The roof is removed (3 door vehicles only).
If the windscreen wipers are in operation and reverse gear is selected, the rear wiper will
automatically operate at slow speed, irrespective of rear wiper switch position. The rear
wiper will stop operating when reverse gear is de-selected.

OPERATION
Rear
General
Feed from the positive battery terminal (C0192) is provided to fusible link 3, and fusible link
4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) is
connected to fuse 30 and fuse 14 of the passenger compartment fuse box (C0587) by an
NW wire. Fuse 30 (C0583) provides a constant battery feed to the rear wiper relay (C0124)
on a PR wire. Fuse 14 (C0583) provides a constant battery feed to the 'Roof On' switch
(C0497) on a P wire.
Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the
ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to
fuse 1 of the passenger compartment fuse box (C0588) on an NW wire. The ignition switch
(C0028) also provides a feed to fuse 8 of the passenger compartment fuse box (C0588) on
a G wire.
Wiper
The CCU (C0592) monitors the condition of the wiper switch (C0079) by providing a feed via
the passenger compartment fuse box (C0589) on an RG wire. When the switch is pressed,
current flows across the switch contacts (C0079) to earth on a B wire. When the CCU
registers this earth, it provides a feed to the rear wiper relay (C0124) on a YB wire. The rear
wiper relay contains two independent relays; a forward relay and a reverse relay.
The energised forward relay (C0124) is now able to provide a feed to the wiper motor
(C0388) on a GR wire. Current flows across the motor windings (C0388) and back to the
rear wiper relay (C0124) on a G wire.
To move the wiper back, the CCU (C0429) removes the feed to the wiper relay on a YB wire
and provides a feed on a YW wire. This feed energises the reverse relay, which is earthed
on a B wire.
The energised reverse relay (C0124) is now able to provide a feed to the wiper motor
(C0388) on a G wire. Current flows across the motor windings (C0388) and back to the rear
wiper relay (C0124) on a GR wire.
Off-Screen Park
The CCU (C0428) monitors the off-screen park function of the rear wiper (C0388) by
providing a signal feed on OB and NG wires. For more information on the off-screen park
function, refer to the Wipers and Washers section of the Workshop manual.

hope this helps
it looks like you can check the motor by putting volts across gr and g to move it forwards and g and gr to move it back.
