Fixing headliner rattles '99 coupe with sunroof


Recommended Posts

I have had a rattle inside the headliner, between the rear window and the sunroof, and have followed the procedure for partially taking off the rear half of the headliner.

What I found inside was a loose piece of weatherstripping, about two feet long, just lying on the headliner. I suspect it may be part of the sunroof assembly, but have no clue where it goes:

The weatherstripping that surrounds the sunroof opening is intact, so I don't think this piece is supposed to be attached to the sunroof panel itself. But it is about the width of the sunroof. Maybe on bottom rear edge of sunroof? It is too short to be part of the rear window sealing system. I'm thinking that maybe over the years the adhesive dried out, and weatherstrip just rattled off of whatever edge it was on.

Any ideas? Is there an exploded view of the sunroof assembly that might show this weatherstripping? What would be be best adhesive for re-attachment?

While I was at it, I noticed that when the sunroof is closed, I can push up the rear part of the sunroof headliner - but the roof itself stays on place. Is that normal?

Thanks.

Does one of the edges have a roll / bend to it? If so it goes on the top lip of what might be called a rain guard. Mine was missing and I replaced it with that part. You can see where it goes when the sunroof is in the up position. Your pic seems like the part and it should be the exact size of the lip. hope this helps.

Yes, that was it. It fit as you described. Just wondering whether the curl is supposed to curl forward, or toward the rear of the

car, for reduced wind noise. Before I glue it down.

Thanks

This stripping got loose also from my car, but only half way off. We were driving quite fast on the autobahn last summer, heard a horrible sound at a speed of about 200 Kmh (120 Mph). Stopped immediately, it was only this part that had gotten loose from the sunroof hitting the top the roof.

Here is what I found on my '01 that had a sunroof rattle only when the roof was open.

 

Operate the roof so that it is tilted, and then look along the back edge of the frame.  There will be a drip pan that is spring loaded, and a weather strip piece attached to it.  If the weather strip is missing or just laying there in the drip tray, the drip tray will move up and down going over bumps and make a bad rattle.  See pic- the screwdriver points to the drip tray, and you can see the rubber strip in place.

 

Clean up the pieces, glue the weather strip piece back on, and the rattle should go away.  My roof is silent now!
