Power Windows

A battery positive and negative connection to either of the two motor terminals will cause the motor to rotate in one direction. Reversing current through these same two connections will cause the motor to rotate in the opposite direction. Each motor is controlled by the Drivers Door Module (DDM).

The DDM controls the logic for the power windows. The DDM receives a mixed input from each window switch. The DDM uses the information to control the operation of the power windows if the ignition is in Run or Accessory (including delay).

An auto-down feature allows either window to be lowered all the way, even if the window switch is released. Each window has a switch that must be depressed in the down direction to a second detent to begin the auto-down function. Depressing the switch again in any direction will immediately stop the window.

Another feature is Smart Glass. The window glass is designed to slide up into a seal to prevent the windows from "popping" out at high speeds. To prevent the glass from hanging up on the seal, the DDM drops the glass when the door is opened, and returns it to the full up position once the door is closed.
