sorry for not being clear, and
my final answer is:
The third brake light is not working which is extremely likely my fault. Therefore I unplugged it.
There are either 2 reasons I can think of why it is not working.
I tried taking out one of the bulbs (never succeeded) and could have damaged it then. Also when I thought I was pulling the plug/harness part, i was actually pulling the entire soldered wiring from the board that holds the bulbs. I can still insert the wiring into the soldered holes in the boards, and it still stays in place.
