Hey Guys I'm new here and just bought my first Blazer. Its a 97, its a sweet truck and I love driving it. anyway my question is going down the road at like 55 the truck runs totally smooth, but the mirrors vibrate real bad you almost can't see anything out of them. I was wondering if you guys had the same prob or knew how to fix it. Not a huge prob but irritating.

Thanks for the help guys later

ps sorry if i'm whining about a common prob it just bugs me

 

I got the same problem on my 97 2dr. The drivers side vibrates but the passenger is ok. Know it doesnt help but thought I'd see...

 

I had the same problem on my 97, 2 door. The passenger mirror would shake like crazy. I bought a new POWER mirror for about $36.00 including freight on the net. I installed it and the mirror does not move at all now. When I removed the old mirror, I noticed that where the mirror mounts to the door, there was a crack in the plastic.
Hope this helps!!!!!
