Interior

Rearview Mirror Vibration

I had a problem with my inside mirror and fixed mine, the button was on the glass solid but the
mirror was vibrating on the button. I decided to take a look at it and see if I could figure out the
problem. I wiggled the mirror while applying upward pressure and it slowly moved up and off
the button, the mirror has a tongue that slips down into a channel in the button, you can't see it
from the inside or outside, you have to take the mirror off to see it. Once the mirror was off I
saw that there are 2 metal tabs that keep the tongue tight towards the windshield. I figured that
over 14 years maybe they were just a little tired, so I took a flat blade screwdriver, put it in the
grove in each tab and gave it a medium-light tap with another screwdriver's handle. I slipped the
mirror back in the grove and no more vibration. I only tapped them once each and lightly, I
could hardly see that the tabs had moved, but since I was afraid of moving them too far, or
hurting the windshield, I figured I could always try again if it was still loose, but one tap each
was all it took. I don't know if all generations of sharks have the same anatomy in their mirrors,
but it worked for my 84.
