I need some assistance here... yesterday while driving the car....I went to roll the drivers side power window down and heard a pretty big metallic bang.

.
and then the window no longer worked... it was stuck about halfway down... I tried using the switch to get the window up and I had nothing at first... except that the motor worked going down while trying to roll the window down...I noticed a cable that started creeping up between the inside of the glass and the window seal..
While trying to roll the window up I heard no window motor at all.. I could grab the window and manually push it up but it wouldn't stay...it dropped back down to about halfway up..
I kept messing with it and for some reason it seemed that the motor worked and the window started rolling back up... I finally got it all the way up and closed tight.. Now, I obviously don't want to try anything else until I can get the door panel off and look at what I have inside in there and how bad it might be..
Does anyone have any ideas about what happened and how do I get he door panel off... by the way, I tried downloading the manual for the Camry on this website but I can't get the .rar to work so I can download and read the manual..
Help me out here...
Thanks in advance,
Kevin
