Haven’t tested voltage yet. I was hoping someone here has bumped up against the issue and knew which fuse handled this. It seems there was a change in 2020, as prior years were not fused and issues resulted.

ok this is what I would do.
- check if any other mirror functionality is affected. the power tilt/move and the defogger and the turn signals if you have them built in
- if the above are all working except the puddle lights, then disconnect negative and positive battery terminals and wait 10 minutes. put the OEM bulbs back and make sure the bulb leads are not crossed and there is no damage to the socket (and nothing inside the bulb is damaged). attach positive, then negative battery. start car let it everything reset and then test the lights again
- if that doesn't help. then get a test light and test every single fuse in the engine bay and under steering wheel
- I suspect step 2 or 3 will solve for your problem. but if it doesn't there's more detail below
in the 2017 MY at least the puddle lights are controlled by the main body ECU (see pic below). I don't know if the wiring diagram is different for 2020 MY, rigtec can probably help with that. if the wiring hasn't changed and there are no fuses blown then the issue is somewhere in the wiring on the main body ECU

Exactly what 1engineer said, they're designed to operate on a momentary basis; they won't stay on as they're wired. So to use an independent switch to control them you would have to canabullize the MB-ECU wiring: "and who knows what will happen as a result"!
