How to fix the annoying visor rattle

Rattles in a vehicle can be so annoying. One of those rattles I noticed in my Jeep Grand Cherokee was when the visor on the passenger was down. The "vanity mirror" has little bumpers, and the mirror is just loose enough so that it rattles quite incessantly. It is especially bad at slower speeds because the bumps in the road are magnified at slower speeds. 

I had toyed around with an idea for some time, and finally got around to trying it. Some time ago I had purchased some assorted sizes of felt pads. I took two of the smaller ones and stuck them to the bottom of the mirror cutout on the visor right where the little bumpers hit when the mirror is down. You can see the two dark spots on the image above on either side at the bottom of the mirror. Those are the small felt pads I attached. They don't show at all when the mirror cover is down, and don't bother when the mirror is showing.

Viola! That solved the problem. No more rattles, no more cursing under my breath about how much technology goes into developing a vehicle and they can't even make a mirror that doesn't rattle. 

Try this simple little fix. It works!
