Switch, Sunroof: Operation

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

The power sunroof switch is hard wired to the electronic module integral to the power sunroof motor. The electronic module provides the switch with a source current whenever the status of the ignition switch is ON or ACCESSORY. When one of the switch push buttons is depressed, it sends a signal back to the electronic module and the electronic module controls the motor to move the sunroof panel to the appropriate position.

A short duration (less than 800 milliseconds) press of the switch push button is interpreted by the electronic module as an AUTO (also known as express or one touch) command, where the motor will automatically move the glass panel to the fully open, fully closed or the ventilation position. A long duration (greater than 800 milliseconds) press of the push button is interpreted by the electronic module as a manual command, where the motor moves only as long as the push button is held in the depressed position. During an AUTO event, any new switch input will immediately stop the event in progress which, as in the manual mode, allows the customer to stop the sliding glass panel at any desired location.

The power sunroof switch may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information.
