Door Glass Operating Mechanism







The windshield, which is of 5 mm laminated glass with a black obscuration band and has the interior mirror fitted, is common to the coupe and convertible. The windshield finisher is a one-piece, single color unit with seal. The backlight is 4 mm tempered glass, green tinted and heated. The windshield, backlight and quarter lights, except for the convertible model, are direct glazed to the body.

The windshield and coupe backlight are supplied as assemblies complete with trim which is secured to the glass by clips and is fully demountable when the assembly is bonded to the vehicle.

The convertible backlight and outer seal are conventionally glazed to the inner seal, which is stitched and bonded to the top. On both models, the heated backlight remains on for 21 minutes after being switched on unless it is manually switched off before the time delay expires. Some backlights are fitted with a security antenna. A fine wire heated windshield offered as an option on some markets, is controlled from the air conditioning panel.

The door glass on both models is a frameless system with 5 mm green tempered glass. The window glass is operated electrically and raised and lowered by a scissor mechanism.

Each door glass automatically drops 12 mm when the door is opened or when the convertible top is raised or lowered, closing when either the door is shut or the top is fully raised and latched in position. The door glass can be closed via the remote control unit. Glass operation is internally controlled from switchpacks located in the driver and passenger arm rests via the driver and passenger door modules. The switchpacks are illuminated when the sidelights are on.

One-touch up operation causes the door glass to fully close unless an object is detected or if the glass is already within 45 mm of top of travel when the door is opened. On detection of an object, the glass will drop fully open or to 200 mm below the obstruction. All door glass operates with the ignition switch in either position I or II and after ignition is switched off, until either door is opened.

Before commencing work within a door interior, all Warnings and Notes within the appropriate Removal and Installation procedures must be read and fully understood.

Rear Quarter Glass Operating Mechanism







The coupe rear quarter glass is a fixed 4 mm, tempered, green-tinted unit direct glazed to the tonneau. The rear quarter glass of the convertible is 5 mm, tempered, semi-flush and green tinted. A drum and wire lowering and raising system provides automatic full glass drop when the top is lowered. Rear glass control is incorporated in the convertible top switch and operation of the rear quarters is as follows.

Raising with convertible top raised:

Activate by pressing and releasing the front of the switch.

Lowering with convertible top raised:

Press and release the rear part of the convertible top switch (one touch down).

When lowering the rear quarters at vehicle speeds up to 16 km/h (10 mph), failure to release the switch on operation of the audible alarm will result in lowering of the top.

Rear quarter glass is automatically powered to the bottom position when the top is lowered and further operation is inhibited until the top is raised and latched.

General Operation

The rear quarters are operated automatically up or down respectively when raising or lowering the convertible top. When the top is raised, with the door glass at the top of its travel, the glass will be powered down 12 mm and the rear quarters will be powered to the bottom of their travel. When the top is fully raised all glass will be powered up to close, forming a seal with the top.

If the front glass has been either fully or partially lowered manually, the rear quarters only will be powered up. If the power supply to the driver or passenger door module is disconnected (battery disconnected, module unplugged or fuse removed) then the glass/system must re-learn the glass operating characteristics. The last known glass position is regarded as top of travel by one touch operation until re-learning has taken place. One touch down, manual up and down control and the automatic lowering of the glass for door opening are unaffected.

To re-learn the glass operating characteristics, the associated door must be closed (door ajar switch inactive). The glass must then be driven fully down and held stalled at the bottom of its travel for a minimum of one second. The glass is finally driven to the fully up position and held stalled for a minimum of one second. The re-learning procedure must also be accomplished to regain the automatic glass closing sequence.
