Driver door glass

[desertt5]

My driver side door window has come loose at the bottomat the back corner from the track/holder it used to be bonded too. You can see the the corner of the glass move in and out depending on wether you are puting the window up or down all the way.

Any easy way to rebond this thing? Looking for alternatives to pulling the entire window/ door apart to reglue it in. I am assuming it was glued originally.
