Can you get to the antenna on the roof externally, or must you drop the headliner to access?

You have to access it by lowering the head liner at the rear, just enough to get to the get to it.

Welcome

A transmission flush and fill x 3 will replace 97% of the fluid.

I recommend  10 amp wire on that branch. 7x 0.5= 10.5

Sounds like a bad switch, I would remove the switch and check it with a Volt/ohms/ Meter.

I will replace the half shaft,  which would require an alignment to be done wouldn’t it?

No alignment needed.

Why Then does, (NHTSA), list:

88T4Z-78264H27-A Edge/MKX Front Latch, Left Side 1
8T4Z-78264A26-B Edge/MKX Front Latch, Right Side 1
8T4Z-7826413-C Edge/MKX Rear Latch, Left Side 1
8T4Z-7826412-C Edge/MKX Rear Latch, Right Si

Replacement for door ajar?

I would call the concierge and question this, if not satisfied, then contact NHTSA and have "them" explain why the dealer won't replace the part needed.
