ELECTRIC WINDOW OPERATION

(RHD shown, LHD similar)

1. Window switch
2. Window lift ECU
3. Window relay
4. Glass
5. Regulator
6. Motor

The two window lift system is controlled by switches fitted in the centre console. When the ignition is switched on, the electric window relay located on the passenger compartment fusebox, switches power supply to the window circuit. The electric motor via an integral gearbox, operates the regulator assembly to lift and lower the window glass.

Battery supply from the electric window relay to the window switches is via two fuses, one for each door, located in the driver’s compartment fusebox.

The driver’s door window has a ’one-shot’ down facility which allows the window to be fully lowered with a single press of the window switch. This is controlled by a window lift ECU which is located at the bottom of the ’A’ post, behind the carpet. The ECU controls all functions of the driver’s window. The passenger window remains controlled by the multi function ECU and the window lift relay as on previous models.
