Thanks all for the ideas and consolation. After a couple hours in the car, I figures out two solutions: one really simple, and one silly and a bit more work. To follow up with a few of the ideas: The car does not assign the list alphabetically (or reverse alphabetically), and it normally wants to add the new door on the bottom. But not always, hence my frustration... Anyway, here's the fixes:
The Easy Solution (that I figured out last, of course)
- You're unable to switch locations directly, BUT you can do the opposite: I clicked on my "Right Door" entry, and then within that entry you can reprogram it... So I could reprogram it with the left door opener, and then simply change the name to "Left Door" and the order was preserved! Voila, easy fix.
The Other Solution (that I committed to first and spent almost...)
- After trying and trying to delete the garage door entries and get them in the right order - each time climbing out of the car an up into the rafters to press the "learn" button on my garage door motor - I finally saw another way: Add a third door!
- Instead of messing with the two doors, I just added another - third - new entry. This one I called "RRight Door" and it added at the bottom of the list, and showed up on the right (of the three) buttons, which now read "Right' "Left" "RRight"
- I then went in and deleted the original "Right Door" entry entirely, leaving just "Left Door" and "Right Door" in the correct order. Then went and fixed the spelling of Right, and perfecto, Problem Solved!
I've got to imagine that in a software update Tesla will add the ability to assign garage door locations - since most tend to be next to one another, but very happy this is solved for me now! Hopefully this will be of use to anyone else flummoxed by the same conundrum.
