Passenger side door handles and taillights not working

Hi,
I've got a 2016 Model S now with 70k miles and last weekend both door handles and the taillights on the passenger side stopped working. The handles do not extend and the parking lights in the rear do not work. The inner brake light (lights on the tailgate) on the passenger side does not work, but the outer one does. Does it sound like a bad ground or blown fuse? Any suggestions on what to look for? Tesla has rescheduled my appointment, so I can't use the car at night without risking getting pulled over. I find a lot about door handles and foggy taillights, but nothing about this problem.
Thanks

It looks to be a controller for that side (or grounding for that side) as Tesla is using that kind of modules to group certain elements. Door controlling modules does lies behind the door panels and if I remember correctly there is one controller for one side (for doors and windows). As the controller is inside the door (front door, if not mistaken) then one place to look for is the linkage between door and car. These wires can be damaged there and if it’s then ground wire you will have big mess. Secondly it can be a blown fuse as well.
Attached is a overview of windscreen washer bump and washer fluid level sensor section form the wiring diagram and there is seen also rain and light sensor attached to that controller.

Thanks. I pulled the lower panel below the glove box to find the fuse panel. (not sure why they made the fuse panel so difficult to access) All of the fuses I checked were good. I looked at the wiring harness between body and door and it looked good. I pulled the front door panel on passenger side and could not find anything that looked suspicious.
