I think the door has come off the track or what ever it rides on or in, it won't close. whats the best way to fix it?

Remove panel behind dash and take a peek, although very limited access. Or remove the entire panel where the stereo is mounted. That gives decent access to the motor and the antenna looking screw type drive. It is also possible that the hitch on the door came loose and detached, it's a pain it the rear to work on this.
Have fun

My door is stuck open also. The is a power draw when you hit the switch, but the door doesn't try to move
