Windows and Glass: Description and Operation

GLASS, FRAMES AND MECHANISMS

Window, One-Touch Up/Down
The window one-touch up/down feature is activated by pulling/pressing the window control switch to the up/down position (second detent). This allows the front door window glass to move upward/downward until it is fully closed/open. A momentary activation of the window control switch, while the window glass is moving upward or downward, stops the front door window glass. The bounce-back feature is incorporated into the one-touch up feature. Bounce-back occurs if the window motor detects an obstruction/debris in the window channel. It also occurs if a door window motor initialization is not carried out after repairs or if lubrication needs to be carried out on the door window glass. The rear quarter windows (convertible only) do not have the one-touch up/down feature.

Window, Short Drop - Convertible Only
The window motors monitor their respective door ajar switches. When the window motor senses a door has been opened (by monitoring its door ajar switch) the window motor opens the window slightly to clear the grooved channel weatherstrip. After the door is closed, the window motor senses the closed door (by monitoring its door ajar switch) and the window motor fully closes and seats the window glass into the grooved channel weatherstrip.

Window Glass, Door
The bottom of the door window glass is mounted in 2 window glass clamps which are part of the front door window regulator. Door window glass bolts and spacers provide attachment points for the door window glass and prevent direct contact between the door window glass bolts and the door window glass.

Window Glass, Quarter
The coupe rear quarter window glasses are set in urethane. The convertible rear quarter window glasses are powered and have a full down sensor incorporated to indicate when the convertible top may operate.

Convertible Top Drop Window Function
When the convertible top switch is operated (to raise or lower the convertible top), the smart junction box (SJB) sends a signal on a shared circuit to the 4 window motors to activate a full down operation of all 4 windows. When the rear quarter windows reach the full down position, the full down sensor in each rear quarter window motor sends a signal to the SJB that the windows are in the full down position. At this time, the SJB allows the convertible top to operate (up or down). If the SJB does not see the full down signal from both rear quarter window motors, the convertible top does not operate. Conversely, all 4 windows operate in any convertible top position. This function is to prevent an accidental opening of the convertible top with the windows in the up position causing contact between the windows and convertible top which may result in damage to the convertible top or windows.
