Make sure the window is full up if possible, I used some duct tape and cardboard wedges to hold it up re Ford Manual. Remove door panel. I stabilized the regulator arm with some duct tape (manual says to do it) by putting it through the speaker hole and the hole at 11:00 to the speaker. Disconnect your battery. Unplug the power window motor. Unscrew the 3 screws holding the motor in place and remove. Grease the gear on the motor. It's a little trickey getting the new motor in place. I suggest taping the mounting screws to the socket driver to make the job easier. When attaching the motor, get the screws turned in maybe 3-5 turns so it holds but are still loose, put pressure on the back of the motor and flick your power window button until you feel the gear engage with the regulator arm. You should be able to see or feel the motor torque once it's engaged. Hold the motor tight to the inside door and tighten the screws. Ford's manual says to torque down the screws 4-7 lb ft., but my motor was after market so I didn't go over 4 lb ft.
