Power Windows (Sedan, Coupe and Sport Wagon)
Features of the Power Window system:
- Control of the front and rear door window motors is carried out directly by the GM.
- One-touch operation in both directions on all windows.
- Cable type window regulator used for all windows.
- Anti-trap detection is provided by the pressure sensitive finger guard (same as E38/E39).
- A new style window switch was introduced with the E46. The switch is pulled up to raise the windows and pushed down to lower them.
- The rear window switches located in the rear doors can be deactivated by the pressing child lock out switch in the center console.
- Convenience closing/opening of the windows from the driver's lock cylinder or convenience opening only from the FZV remote key (FZV operation can be owner customized with the Car Memory Function).
- Window operation with the ignition switched off until a door is opened or 16 minutes has elapsed after the key is switched off.
- Window load switching is through relays integral of the GM. The GM V monitors the current draw for end limit position. The maximum run time for the window motors is limited to 8 seconds. This allows the motors to be switched off if the end limit load sensing fails.
