drivers side rear window keeps falling down...can raise it back up with my hands easily but I'm getting tired of doing that. any thoughts? hit the button to go down and the window lowers normally. hit it to go up and the window doesn't move. do nothing and within 30 mins or so the window will have worked it's way down on it's own.

 

if it's cheaper to "rig it" where it won't go down ever again I'm okay with that.

 

I think you'll probably have to remove the inner door panel to have a look at what's going on, before we/you will know.
