Ok if this was my truck this is how I would go about it
1. I would take off the plastic panel around the steering column and see if I can pin point the noise inside the cabin, if it's not in the cabin Then I'd take off the front driver side wheel off, have someone steer the car and I would listen closely near the rack and pinion/steering shaft area, by then I ought to hear and be able to close in on the location of the noise.
2. Seeing #2 & #3 in a similar in location (drivers door) very first thing i would check is to do a visual on the wiring harness in the door jam, by pulling off the rubber boot and closely examining for pinched wires, if that seems to be visually correct then for #2 I would take off the door panel and lube the window regulator and tracks with white lithium grease, reconnect the switch with the panel still off and see if attempting to roll the window has any issues as to where it might be sticking at or if I hear any clicks anywhere indicating a location of interest.
3. If wiring harness inspection checks out for previous step then first I'd checks for any blown fuses that strictly control the power locks just to be sure, then if that is ok, like you i would've replaced the switch and see what happens, and finally if that too doesn't help then I'd tackle changing the door lock actuator, though it isn't a common problem on fords, it is very common on foreign auto makers, and the symptoms of a failing door lock actuator is as you described on your first post with the passenger door lock still working fine.
That would be my course of attacking the problems.
