Description And Operation: General

WINDSHIELD

The laminated windshield is bonded and sealed to the body aperture using PU sealant. Heat bonded to the inner surface of the screen is the optical unit for the rain sensor and the interior mirror mounting boss.

Vertical fine-wire multi-strand elements are fitted between the glass laminations to de-ice and demist the screen. At the bottom of the screen six horizontal heating elements bonded to the interior glass surface prevent the wiper blades freezing to the screen during adverse weather conditions.

The screen is supplied with the heating element flat foil connectors fitted to a sealed terminal block. This terminal block is wired to a connector for connecting to the vehicle harness.

REAR WINDOW

The tempered glass tinted green rear window is bonded to the upper tail doorframe using PU sealant. Fitted to the inner surface of the rear window are the heating elements and antennas.

The heating element is connected by two Lucar terminals while the antenna is connected to the vehicle by a twin and single stud connector at the top of the screen.

ELECTRIC WINDOWS

Electric windows are installed in all four doors. All of the electric windows incorporate one-shot up, one-shot down and anti-trap features.

In each door, the window is operated by a regulator, which is controlled by the related door module in response to inputs from window switches. The door modules also operate the windows in response to inputs from the CJB (central junction box) for global opening and closing.
