Driver Door Window – RHD Vehicles Fuse 34 of the passenger compartment fuse box (C0586) provides a feed to the driver door window switch (C0242) and the window lift ECU (C0341) on SO wires. The window lift ECU (C0341) is earthed on a B wire.

When the driver door window switch is pressed to lower the window, current flows across the switch (C0242) to the window lift ECU (C0341) on an OG wire. The window lift ECU (C0341) now provides a feed to the driver door window lift motor (C0326) on an R then OR wire. Current flows across the motor (C0326) back to the window lift ECU (C0341) on an OU then U wire. The window lift ECU (C0341) is provided an earth path via the driver door window switch (C0242) on an OY wire.

The driver door window switch (C0242) is earthed on a B wire. The window will now move to the fully lowered position.

When the driver door window switch is pressed to raise the window, current flows across the switch (C0242) to the window lift ECU (C0341) on an OY wire. The window lift ECU (C0341) now provides a feed to the driver door window lift motor (C0326) on a U then OU wire. Current flows across the motor (C0326) back to the window lift ECU (C0341) on an OR then R wire. The window lift ECU (C0341) is provided an earth path via the driver door window switch (C0242) on an OG wire.

The driver door window switch (C0242) is earthed on a B wire. The window will now move to the fully raised position.

Front Passenger Door Window – LHD Vehicles Fuse 34 of the passenger compartment fuse box (C0586) provides a feed to the front passenger door window switch (C0242) on an SO wire.

When the passenger door window switch is pressed to lower the window, current flows across the switch (C0242) to the passenger door window lift motor (C0326) on an OR wire. Current flows across the motor (C0326) and back to the passenger door window switch (C0242) on an OU wire. The motor is provided an earth path via the passenger door window switch (C0242) on a B wire. The passenger door window will now move downwards until the switch is released.

When the passenger door window switch is pressed to raise the window, current flows across the switch (C0242) to the passenger door window lift motor (C0326) on an OU wire. Current flows across the motor (C0326) and back to the passenger door window switch (C0242) on an OR wire. The motor is provided an earth path via the passenger door window switch (C0242) on a B wire. The passenger door window will now move upwards until the switch is released.
