SERVICE INFORMATION
A rattle coming from the sunroof area may be caused by the sunroof clips rubbing against the sunshade clips, or against the sunshade finisher. A squeak may be caused by the headliner rubbing against the sunroof frame at the front and rear sides of the sunroof.
To eliminate clip rattle, install a wavewasher to each sunshade lock and install a new flocked sunshade finisher to the sunshade. To eliminate the squeak, install tape between the headliner and the sunroof frame. These procedures are described in this Service Bulletin.
