Power Top - Description

DESCRIPTION





The power sunroof system allows the sliding glass sunroof panel (3) over the first row seating to be opened or closed electrically by actuating a switch located in a bezel on the headliner between the two sun visors. 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 a ventilation position, and slides upward and rearward above the outer roof panel for the open position. The glass panel seals flush with the roof in the closed position to eliminate wind noise, and an integrated wind deflector (2) 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 (1) - Sunroof - Description.
- Manual Sunshade - Sunroof - Description.
- Motor and Module Unit - The power sunroof motor and module unit is secured near the center of the rear frame member of the sunroof, between the outer roof panel and the headliner.
- Sliding Glass Panel - Sunroof - Description.
- Switch - The power sunroof switch unit is secured within a switch bezel centered in the headliner between the windshield opening upper header and the front of the sunroof opening.
- Wind Deflector - Sunroof - Description.

Hard wired circuitry connects the 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.
