Ok, I bought an 06 silverado in July and in the past month i've noticed at 70mph on the interstate my drivers mirror glass vibrates. I had the dealer I work for take a look at it when I had it in for an oil change a few days ago and I ordered a new mirror for it. It was a warranty part so no biggie. They installed the mirror on Thursday night and on my way home, on the interstate, I notice that the vibration is still exactly the same. I am wondering if anyone has experienced this and if so what did you do. It's not a vibration sound, the glass itself shakes. I do not have ventvisors or a bugshield, so I am unsure what is causing this......

 

my 03 is the same. The thing that bugs me the most is that it looks like the passenger side is not vibrating at all.

 

yea i had the same things, there is suppose to be a rubber gasket behind the clip that holds it on, you could always take the mirror off to make sure its there. i found this out when my mirror broken and the guy at the dealer left it out

 

i havent noticed it, but my mirrors vibrate cause of my stereo

 

mine have always vibrated..

 

.....werd. And yes my pass. side also looks fine at all times, hmmm, maybe ill just have to deal with it.

 

Same here, however its alot worse if I have my windows down from 50mph up! Pass side just sits there nice and quiet too!

 

All of these replies make me want to investigate this more......
