drivers side mirror problems

[brake]

First of all, I should say my power mirrors don't power. I can manipulate both mirrors by hand and get them in the right spots so I can see out of 'em, but the drivers side has play in it and wobbles around when in motion and consequently will work itself out of position. It's really damn annoying.

 

 

 

What would cause the glass inside the door mirror housing to not stay in place?

 

 

 

I haven't bothered troubleshooting the mirrors not being powered because I don't really need the function. Would be nice to have but I don't care enough....I just want the mirror to stay in one position.
