Trouble Diagnoses: Weatherstrip

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

In the case of leakage around glass lid, close glass lid and pour water over glass lid to find damaged or gap portion, remove glass lid assembly. (Refer to removal procedures, REMOVAL AND INSTALLATION , for details.)
Check weatherstrip visually for any damage, deterioration, or flattening.
If any damage is found, replace weatherstrip.
CAUTION: Do not remove weatherstrip except when replacing, or filling up butyl seal.
