Please HELP with this weird electrical problem

[acharania]

I have a 2016 Nissan Rogue SV and both the side view mirrors (door mirrors) are not working. On the left, the turn signal light works but on the right, the turn signal light is also not working. I have done the following troubleshooting:

Already replaced the remote switch with brand new one.
Thinking that the mirror assembly/motor was bad, I replaced it with a working one but no change.
Checked all fuses in the driver side and find that three switches are not getting power at all. These are fuse numbers 19, 20 and 21. As per service manual Mirrors.pdf, it is fuse number 20 that powers the door mirrors.

How do I continue further troubleshooting to find why these fuses are not getting any power? Please help.

Anytime stuff in a door on a gen2 Rogue doesn't work, the first thing to check is the door umbilicals. Peel back the rubber boots and look for this sort of cracking and fraying:

The door mirrors on a '16 are a straightforward 4-way switch setup, you can find the wiring diagram starting on MIR-10 here:
