Problematic passenger window!

2005 Access Cab with 120k on 'er, I bought it 2 years back at 55k, no wrecks (to my knowledge).

It has power windows and, a few months back, I noticed the passenger door would make a loud pop/creaking noise when opening/closing. I didn't get a chance to pull it apart and it's since stopped. Now, a few weeks ago the door no longer makes any noise when opening. However, it now pops open after you pull the handle...and the door window only rolls down about 1/3 of the way. I've taken on a few more projects and haven't had time to pull it apart.

I didn't see anybody else with similar issues, so I thought I'd see if anybody had thoughts...thanks much!

 

Window has either fallen out of the track, or something with the locking has come loose and is blocking the window. Or could be as simple as the track needs to be lubed..
