Tail Door Window General

The console mounted switch (C0263) is earthed on a B wire. The window will now move upwards until the switch is released.

NOTE: Both rear door window lift motors, and both rear door mounted switches have the same connector numbers as they utilise the same harness.

Tail Door Window General

Feed from the positive battery terminal (C0192) is supplied 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 14 and fuse 31 of the passenger compartment fuse box (C0587) by an NW wire. Fuse 31 (C0583) provides a constant battery feed to the tail door window lift relay (C0043) on a PN wire. Fuse 14 (C0583) provides a constant battery feed to the roof on switch (3 door vehicles only) (C0497) on a P wire.

Fusible link 4 (C0574) also provides a constant battery feed to the Central Control Unit (CCU) (C0593), via the passenger compartment fuse box (C0587) on an NW wire. The CCU (C0593) is earthed via the passenger compartment fuse box (C0587) on a B 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 to fuse 8 of the passenger compartment fuse box (C0588) on a G wire. Fuse 8 provides an ignition feed to the CCU (C0593).

Tail Door Wiper Motor

The CCU will not operate the tail door window if the rear wiper is operational. The CCU (C0428) monitors the condition of the rear wiper by providing a feed to the 'off screen' park switch (C0388) on an OB wire. The 'off screen' park switch is open circuit at all times except when the rear wiper is in the park position. When the wiper is in the park position, current flows across the switch contacts (C0388) to earth on a B wire. The CCU will only operate the tail door window when it registers this earth path.

The CCU (C0428) also monitors the position of the rear wiper by providing a feed to the 'on screen' switch (C0388) on an NG wire. The 'on' screen switch is open circuit at all times except when the rear wiper is at the top of its travel. At this point, the switch contacts close, and an earth path is created on a B wire.

NOTE: The rear wiper will not operate if the tail door glass has not been calibrated.
