Switch-Power Top: 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. The driver window regulator module uses this CAN B message to perform one of the following functions:

  1. Power top up (switch pushed upward)
  2. Power top down (switch pushed downward to the first position)
  3. Power top express down/all windows down (switch pushed downward to the second position and held in place)
