All the lights in trunk don't work. Need some help! ~ Sloved

Working on a 2004 SL500. All the lights in trunk don't work.
1. Trunk light
2. Easy access for the top (red button)
3. The Emergency green flashing light.

Within SDS, under one page, I can manually turn on the trunk light and the easy pack Red light with SDS but they won't stay on. Just illumination. Not functional for the easy pack.

I recalled 1 time (yesterday) I went inside SDS and saw a page where I can set the Trunk light to "ON or OFF", and other lights work as well after that. Exercised many times and everything seem normal. Which means Top stowed in trunk and red button raised it up and down. Trunk light stay on at all time when trunk is open. Guess I zipped through it so fast now I forgot.

This morning I opened the trunk and everything back to square one. I was wondering if someone can give me an idea where I can find that page again. It burried deep down somewhere.
TIA

Problem Sloved!!!

Again, the beast we own is really current sensitive.

As I stated before, I can turn them all on individually inside SDS. That mean wiring are good, bulbs are good, right! Not really.

Porblem is, the car is 15+ years old. Spilled fluid, dirt, dust from the pass along with current flowed through those connector pins. Basically a thin flim of those nasty stuffs were cooked on the surfaces of pins/receptacles. Created a great deal of resistances. Onboard computer circuitry just terminated the output. After I soaked, scraped all the pins, All things start working inside the trunk now. In this case, SDS is actually screwed up my trace of thought
