Default Trunk Lid Rear Fog/Brake Light not working even with new bulbs

The (right) passenger's side inner trunk lid rear fog/brake light is not lighting up.
The (left) driver's side inner trunk lid rear fog/brake light is working fine, both with fog on and off.

I have replaced both side with new bulbs. I have also switched the bulb holder between the left and right, but the passenger's side is still not working. I measured 13V on the left side, but no voltage on the right side. I have also try to measure directly at the right side bulb connector, but it still reads 0V. I have also try to measure the + at the right side bulb connector with - at the left side connector to eliminate grounding issue, but it still reads 0V.

I could not find the fuse for it. I have looked at the owner's manual. The fuse # that the manual refers to is empty in the fuse location. In other words, the fuse is not even in the fuse box. I think the manual might be outdated. I have also looked at the fuse label on the cover. I still couldn't find it.

Does anyone have any suggestion? Perhaps could someone tell me which fuse#?.
