Strange window problems
 

So I have a very strange issue going on with my driver side window that I'm completely stumped on how to fix.
When I push the button down so window rolls down it doesn't, but when I pull up on it, it goes down slightly and then rolls back up. sometimes it'll go down about half way and when I push the button down, it'll roll back up.
what the hell is going on? does anyone have any idea on how to fix it? anything would be helpful.

I'm afraid it is a window regulator problem.
