I have seen a couple of threads where someone has complained about their mirrors vibrating while driving. Today I was reading my owners manual (gotta do something while I wait for my truck) and I came across the answer.

Loose Mirror
If your power-folding mirrors are manually
folded, they may not work properly even
after you re-position them. You need to
reset them if:
• The mirrors vibrate when you drive.
• The mirrors feel loose.
• The mirrors do not stay in the folded or
unfolded position.
• One of the mirrors is not in its normal
driving position.
To reset the power-fold feature, use the
power-folding mirror control to fold and
unfold the mirrors. You may hear a loud
noise as you reset the power-folding
mirrors. This sound is normal. Repeat this
process as needed each time the mirrors
are manually folded.

 

Yep that's often the problem. I've seen folks say that isn't the case, but then again, it's the internet. No one likes to be proven a fool.

 

You could also turn the music down,...mine really vibrates with the volume up. The Bass is awesome!

 

thanks for the tip!
