This is a great write-up! Thanks!!
I would add a few points with regards to the front door.
My window froze in the down position. The switch activated a clicking sound in the door but the window would not budge. The switch seemed to work but the motor seemed shot.
If you think it's the motor DO NOT REMOVE THE REGULATOR!!! You don't need to in order to replace the motor. The motor comes out independent of the regulator. No rivet drilling, no replacement bolts or any of that!!! If it's not the regulator - leave it alone except to lubricate it!!
Drilling the 1/2" hole is no big deal but do not go too far, be gentle, the bolt is right there. (Ford™, PLEASE HELP US UNDERSTAND WHY THE DIMPLE AND NOT A HOLE???)
Remove the speaker and all the mysteries of the inner door are revealed. You can see the motor and get your hand in there to remove it.
For me, prior to installing the new motor, I removed the old motor, plugged in the new motor to test it and discovered it worked fine. And then, for the hell of it, I plugged in the old motor while it was out to test it. IT WORKED FINE, TOO!!!
I generously lubricated the regulator tracks with lithium grease and sprayed some Tri-Flow™ into pivot points, reinstalled the OLD motor and ran it for a good quarter hour; up and down, down and up - works like a charm!!! Better than before! Maybe a loose connection or a rusty joint or track??? Who knows?
Took the new motor back to AutoZone®!
