When riding in my mustang my mirrors virbrate violently. They seem to be loose. Anyway to tighten them? They vibrant even if i have my stereo off. Any suggestion. Any help would be greatly appreciated.

 

I beleive that all you need to do is pop off the speaker grill or something and take off th speaker and the bolts for the mirror areright behind there. I had to do it for my passenger mirror once. Hasn't come loose since.

 

Thank you very much!
