Headliner Sag at Rear of Sunroof Opening (Replace Velcro Patches)

Some customers may comment that the headliner sags at the rear of the sunroof opening.

The Velcro® patches on the underside of the sunroof module may have been installed off location. The Velcro® patches on the sunroof module and the headliner may not align.

1. Carefully pull down the headliner at the rear of the sunroof opening and verify the alignment between the Velcro® patches on the sunroof module and the headliner.
2. If the patches are misaligned, insert a small block of wood between the roof and the headliner in order to provide access to the patches.
3. Remove the patches on the sunroof module.
4. Clean the surface of the sunroof module using one the cleaners listed below.
5. Install two new Velcro® patches, from the service kit (P/N 88952325), on the sunroof module making sure the patches are properly aligned with the headliner patches.
6. Remove the block of wood and push the headliner back in place so that the Velcro® patches are fully engaged.
