Rear Door Vent Window

Print

The rear doors have a movable vent window which can be either manual or electrically operated. The window is held in place by mounting screws in the upper door frame and the door belt return flange.

The manual vent window has a latch handle which locks or opens the window.

The electric vent window is operated by an electric motor and a drive cable assembly. It is controlled by a master switch on the left front armrest or on a switch on the rear door trim panel.
