Operation CHARM: Car repair manuals for everyone.

Power Sunroof

The Accessory Delay Relay 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.

The control of the sunroof is done through the switch to the sunroof control module. The control module is located in the roof.
