The driver'* side mirror in my '95 Bonneville - Bridget - vibrates, even at city speeds (it'* worse at highway speeds.) Is there a) any particular reason for this and b) anything I can do about it? Mind you, the mirror is still fully attached to the door and nothing is visibly loose.

he whole housing or just the glass? my whole housing was and the mirror is brittle plastic and broke i tried epoxy that didnt hold any better im afraid a new housing is the only way

So far, I've only noticed the glass...but thanks for the heads up if it is the entire housing as well!

The mirror glass is attached to the back plate with glue, the back plate is attached to the mirror mechanism at 3 snap points (circled in red) and the mirror mechanism is attached to the mirror housing at 4 points (circled in green). Your mirror may be a different design, but the attachment features will be similar.

Check the 2 screws at the bottom of the housing to make sure they are tight. Checking anything else will mean unsnapping the mirror from the mechanism, confirming all attachments, and snapping it back in place.

Thank you! The images were helpful in giving me an idea of what to look for on the mirror.
