I have a 2000 TL. At some freeway speeds there is an annoying vibration noise that can be stopped by grabbing onto the rearview mirror.

I imagine this is a common problem and would like to know if anybody has a simple fix or work around.

I also have had the noise with the seatbelt latches, and I'd heard some people have used soap as a lubricant there. But that one hasn't bothered me enough to do anything. I would love to fix the rearview however.

 

Is your mirror shaking on its mount? If so, I have a potential fix.

About a year after I replaced it, my rearview mirror would start to work its way off the mounting bracket. It didn't make any noise but it could tell it was loose from the shaking of the reflected image. Attempting to push it more firmly into place did not help. I didn't want to apply too much force because others have cracked their TL windshields doing this.

So here's what I did to correct the problem. I removed the mirror entirely and I applied a very thin coat of silicone sealant between the two interlocking sections of the mounting bracket. I did that months ago and the mirror has not loosened since.

 

Thanks for the suggestion. I'm not sure where the loose point is. The image in the mirror appears stable and the mirror doesn't seem loose. Some damping is probably what it could use though and if that is where the motion is something silicone might do the trick.

When you say silicone sealant, is that like caulk, or something else?

Do I need to pull out the sunglasses holder and all that to access the mount, or just remove a cover on the rearview mirror?

 

Yes, silicone sealant is a type of caulk. It doesn't have to be silicone. There are latext based sealants that should work fine also. Just use a very small amount so that you can remove the mirror, if needed, down the road.

For directions on how to remove the mirror, along with some photos, see this link:

Thank forum member Ksuchdeve for that.

 

i have the rearview mirror with all the onstar options and fancy buttons that i know nothing about and my subwoofers make it rattle terribly...dont know if its just such loud bass that everything is shaking or if there was something that could be done for that as well
