Defender is now fitted with electric front windows, which operate when the ignition switch is turned to the 'ignition' position. The window lift switches are non-latching, and are located on the fascia console.
Operation
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to fusible link 1 and fusible link 5 of the passenger compartment fuse box (C0632) on an N wire. Fusible link 1 is connected in series with fusible link 3, which is also located in the under seat fuse box. Fusible link 3 (C0571) provides a constant battery feed to the ignition relay (C0218) on an NR wire.
Fusible link 5 (C0570) provides a constant battery feed to the ignition switch (C1043 on LHD, C0028 on RHD) on an NW wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C1732 on LHD, C0094 on RHD) to fuse 15 of the passenger compartment fuse box (C0580) on a W wire. Fuse 15 (C0580) provides an ignition feed to the ignition relay coil (C0218) on an LGP wire. The relay coil (C0218) is earthed on a B wire.
RH Window
The energised ignition relay (C0218) provides a feed to fuse 34 of the passenger compartment fuse box (C0595) on an NS wire. Fuse 34 (C0595) is connected to the RH window switch (C0242) by an SO wire.
Up
When the window switch is moved to the 'Up' position, current flows across the switch (C0242) to the RH window lift motor (C0326) on an OR then R wire. The window lift motor (C0326) is provided an earth path via the window switch (C0242) on a U then OU then B wire. The window lift motor is now able to power the window up.
Down
When the window switch is moved to the 'Down' position, current flows across the switch (C0242) to the RH window lift motor (C0326) on an OU then U wire. The window lift motor (C0326) is provided an earth path via the window switch (C0242) on an R then OR then B wire. The window lift motor is now able to power the window down.
LH Window
The energised ignition relay (C0218) provides a feed to fuse 35 of the passenger compartment fuse box (C0595) on an NS wire. Fuse 35 (C0595) is connected to the LH window switch (C0321) by an RG wire.
Up
When the window switch is moved to the 'Up' position, current flows across the switch (C0321) to the LH window lift motor (C0326) on an R wire. The window lift motor (C0326) is provided an earth path via the window switch (C0321) on a U then B wire. The window lift motor is now able to power the window up.
Down
When the window switch is moved to the 'Down' position, current flows across the switch (C0321) to the LH window lift motor (C0326) on a U wire. The window lift motor (C0326) is provided an earth path via the window switch (C0321) on an R then B wire. The window lift motor is now able to power the window down.
NOTE: The RH and LH window lift motors have the same connector number as they are derived from the same harness drawing.
