Power Sunroof

POWER SUNROOF
The power sunroof in the Grand Cherokee is controlled by the Body Control Module (BCM). After the ignition has been turned off, the power sunroof will remain operational for an additional 45 seconds. If the front doors are opened during this time, the BCM will remove power from the sunroof.
