Electric WINDOWS
DESCRIPTION
Introduction
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.

4.12 DEFENDER 02MY
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. Electric Windows
The factory switches swap the positive and negative polarities to the window motors (there's no Window ECU in the Defender) the switches switch the motors directly, here's the description of how they work -All the 2002 switches, except the Hazard Warning Switch, are not suitable for switching loads directly - use them to switch relays.

Two ways of doing it, firstly you can replicate the standard wiring:
(Remember pin numbers are looking at the end of the connector, as if you were the switch)

For the front electric windows, there are no relays as standard. The power is run directly through the switches to the motors, and comes from fuse 34 for the RH window and fuse 35 for the LH window. Power is supplied to both these fuses from the ignition relay on a brown/slate wire (4.00mm� - should already be present as I believe it feeds many other fuses - just needs extending to feed the two empty slots).

From fuse 34 a slate/orange wire (2.00mm�) runs to pin 2 of the driver's E/W switch. Then an orange/red wire (1.50mm�) comes from pin 4 and feeds one side of the electric window motor. If you use the standard in-door looms then this needs to connect to the red wire on the RH door motor. The orange/blue wire from pin 3 on the E/W switch (also 1.50mm�) connects to the blue wire in the door loom. There is a black wire (1.50mm�) from pin 1 on the switch which is an earth path, it goes to header 0287 but earth it where you like!

The passenger's window is very similar. A red/green (2.00mm�) wire feeds the switch on pin 2 and there is another earth (1.50mm�) on pin 1 to the same header as before. The feeds for the motor are on pins 3 and 4 as before, and use a blue wire and a red wire respectively (both 1.50mm�). These connect directly to the red and blue wires in the door loom.

Both E/W switches have illumination provided to pin 6 on a red/orange wire (0.5mm�). Take this from the illumination header (0290) behind the centre console.

For what it's worth, I'm planning on doing this method as I have gotten hold of a high-spec Td5 loom and I am stripping all the wires, connectors etc. out of it and I will splice these into my ROW-spec loom.



The other option is as you say to use your own wiring. I wouldn't bother with relays as the switches are designed for the load and you just add unnecessary wiring. You will need:

■Two 20A fused supplies (one for RH and one for LH window) in your aux fusebox.

■Some wiring (preferably four colours, red and blue, black and another for the feed).

■Feed both the switches on pin 2.

■Run pin 3 of each switch to the blue wire in the door loom.

■Run pin 4 of each switch to the red wire in the door loom.

■Provide an earth path on pin 1.

■Illumination on pin 6 if you desire.

■Use either 1.5mm� or 2.0mm� throughout (except for the illumination feed which is 0.5mm�).


■Terminal 1 - Fused Live IN

■Terminal 2 - Dash Illumination

■Terminal 3 - Not Used

■Terminal 4 - Switched Live OUT (to Relay)

■Terminal 5 � Earth

There are no relays in the Defender's Electric Window circuit, the switches do the switching directly.

Make sure you have the later switches, part number YUF101521LNF

. Power is fed from battery into the door (20 amps fuse box satellite through ignition relay) on the driver�s side. This is transferred through the control panel for the window switch to a contact point located at the middle of the switch of each of four windows
