Sunroof is not closing
The sun roof will open all the way but will not close all the way. It remains tilted and will not go down anymore. I replaced the switch and checked the fuse. It still will not close. ANY Suggestions?

    If it remains open just a little , like less than an inch, read this >.

    Sunroof will not close all the way. It remains open about 1/4 of an inch. It will open all the way with no problem.
    Tests/Procedures: 1. When resetting this position, ensure that the sunroof actuator is timed to the closed position.

    2. Do this by verifying that the hole in the large timing gear, the notch in the disk, below the drive gear and the scribe mark on the drive gear are all in line with each other.

    3. Install the sunroof actuator and actuator bolts.

    4. Connector the connectors to the express module and make sure wiring is securely out of the way.

    5. Now operate the sunroof. It should go full open and then full closed.
