Power Windows - Tailgate: Description

Tailgate window system consists of a 12-volt reversible direction motor, internal regulator, and jackscrew type regulator. The internal circuit breaker may require 1 to 3 minutes to reset. Window is controlled by the jackscrew regulator.

The window is operated by an instrument panel switch when the ignition switch is in the "ON" position, or an external key switch located in the tailgate door. The window retracts into tailgate door.

A cut-out switch prevents operation of the window by either switch when the tailgate is open. Circuit is protected by a 30-ampere circuit breaker, located at fuse block.
