If the passenger side switch works I’d pop that out and try it temporarily on the drivers side to make sure that’s not it, even though you checked it already. They are easy to remove.

Believe it or not the switches are actually slightly different. The passenger side would fit on the drivers side. I do have a new switch in order though. Crossing my fingers it’s that simple.
More than likely the mechanical toggles in the driver door switch have become dirty or annealed and are not making contact. The switch can be carefully disassembled and the contacts can be cleaned up.

I have the same issue, only reversed. The passenger side door switch does nothing. The drivers side works and the key fob works.
I have replaced the passenger door switch and it did not correct it. I have not checked the lock solenoid/wiring because the lock still works by the other methods. I havent yet looked for any other relays/components in lone that can be a failure point, primarily because I haven't yet bothered to order a wiring diagram.
I saw a service bulletin about problems with the rear door lock switch causing other switches to not work. It says to test if thats the issue by unplugging the rear switch and then checking to seee if the door locks work properly.
