Ford 7.3L Power Stroke (1999-2003) :: Driver Side Door Panel And Liner Off

I've taken the driver's door panel off, and unpeeled the liner. Now that the door is naked and exposed, I'd like to fix several things at once, rather than wearing the adhesive liner out by sticking and unsticking several cycles.

Here's a short list of some potential fixes I foresee taking care of while in there, how to :

1. The door ajar light. Mine went out over a decade ago, and the gallon of WD40 I sprayed into the latch did NOT fix it. In fact, it turned it from an intermittent issue into a permanent problem. I'd like to fix it now, as I miss having a light at night when the door is open. How do I fix it? Links, part numbers, tips, pictures, videos, search terms... all info welcome.

2. Bottom door rust. I don't really have much, but I see very faint hints of paint bubbling under the lower door weatherstrip barrier, which I have also removed. I've read about two schools of thought on preventative maintenance.

A. Pour oil or grease into the bottom of the door.

B. POR15 paint in the bottom of the door.

So basically, oil or paint? Obviously, one can't paint if one does oil, but on the other hand, some say that paint... especially thick paint like POR15, can actually do more harm than good by trapping moisture in the bottom pinch flange, or by creating craters or tunnels where water can burrow and then get trapped, rotting the metal away. What are your thoughts and experiences on this? I'd prefer a solution that minimizes the number of times I have to unstick the interior liner from the door.

3. I'm doubling the lower door weatherstrip with a combination of the older and newer designs. Ford sells the weatherstrip with clips attached, but neither those clips, nor the original clips, are really effective for what I'm trying to do. I've already done the rear doors, and made it work with the original clips, but they are brittle, and I lost a couple to breakage. Today, I broke three clips pulling the old weatherstrip off of the door.

I can't find these clips anywhere locally... I've tried every variety the auto parts and auto body stores sell, and Ford doesn't sell these clips separately from the weatherstrip... and even if Ford did, they OEM clips are not long enough to hold the double deployment of old and new styles of weatherstripping.

In searching this issue, it appears that a lot of people have broken these clips, which stands to reason with plastic in baking inside a hot door for 15 years. I'm sure I'm not the only one who would benefit from finding a good source of automotive clips.

4. Mirrors. I'm finally getting around to this, and this is what motivated the door panel removal in the first place. I need the dog bone harness that converts from a round connector to the flat style connector. Specifically, I need part numbers 1C3Z-14A411-AA and 1C3Z-14A411-BA. Ford didn't originally sell these dogbone harnesses separately, but included with the purchase of newer style outside rear view mirrors in case the translation harness was needed. Sometimes it was, sometimes it wasn't, so there would often be these unused harnesses left over.

5. Jimmy Jammers. Will they cause more harm than good? Does a better alternative exist? Thinking of installing these while I"m in there, but worried the door will be damaged worse as the thief tries to fight their way in. And, with body on shell doors, there appears to be much easier ways to break into an SD anyway, so part of me thinks, why bother
