Power Sunroof - Description

DESCRIPTION

The information and procedures found cover only the electric motor, electronic module and the switches used for the sunroof. The information covering the mechanical components of the sunroof system can be found in the Body group. Single Pane Sunroof - Description.

The single pane power sunroof system allows the sliding glass sunroof panel over the first row seating to be opened, closed or placed in a ventilation position electrically by actuating one of three switch push buttons located in the overhead console. The electronic controls integral to the sunroof motor and module unit provide an express (also known as one-touch) feature to simplify sunroof opening and closing while driving. The electronics also provide an Excess Force Limitation (EFL) feature, which detects obstacles trapped between the glass and the opening in the vehicle roof during closing.

The sunroof glass panel tilts upward at the rear for the ventilation position, or slides downward and rearward between the outer roof panel and the headliner for the open position. The glass panel seals flush with the roof in the closed position to eliminate wind noise, and an integrated mesh wind deflector reduces wind buffeting at low speeds with the sunroof open. The sunroof also includes a manual sliding sunshade to cover the deep tinted glass panel when closed.

The major components of the single pane power sunroof system include:

- Frame and Mechanism - Single Pane Sunroof - Description.
- Manual Sunshade - Single Pane Sunroof - Description.
- Motor and Module Unit - The single pane power sunroof motor and module unit is secured near the center of the front frame member of the sunroof, between the outer roof panel and the headliner.
- Sliding Glass Panel - Single Pane Sunroof - Description.
- Switch - The single pane power sunroof switch unit is integral to the overhead console centered in the headliner between the windshield upper header and the front of the sunroof opening.
- Wind Deflector - Single Pane Sunroof - Description.

Hard wired circuitry connects the single pane power sunroof system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the single pane power sunroof system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
