1994 F150 Extended cab XLT 4x4

Today the driver's side window quit.
It moved about 2 inches when I tried to lower it and stopped.
The switch has no effect and all other functions on the panel work (passenger window, auto lock and mirrors) I removed the door panel but hesitated to remove the window motor because I can't figure out how to isolate the problem.
Any advice of wiring diagrams appreciated..
Thanks in advance
