Power Top - Convertible: Operation

WARNING: This page is about a different car, the 2006 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

The power top switch status is transmitted using CAN B message. When a top operation message is received by the driver window module, it will ground the respective relay control circuit which in turn will operate the motor. If the convertible top switch is pressed and held to the down position second detent, it will command both modules to drop all windows to the fully down position. The windows cannot be raised when the convertible top switch is in the top down position.

When the switch is held in the top up position and all four windows are fully up, the modules will lower the respective front window 40mm (1.5in.), lower the respective rear window for 0.52 seconds (approx. 55mm (2in.)) and the driver window module will ground the top up relay control circuit. Once the top is back up the windows will not raise automatically. When the top switch is pressed in either position, the driver window regulator module will ground the respective relay control circuit for a maximum of 20 seconds. The window regulator module monitors vehicle speed and if the speed is over 15 mph, the top will not operate. (Refer to ELECTRICAL/POWER WINDOWS/WINDOW REGULATOR MODULE - DESCRIPTION) for additional information on the window regulator module.
