Recently, the three brake lights out order in the same time. And one BBer sent me very detail diagnose instruction.

Here is what I learned from the instruction:

fuse 7 provide 12 V to the brake light switch, brake light switch connect to Bulb Fault Sensor terminal 9, BFS terminal 9 connect terminal 10 and 11 , terminall 10 and 11 connect the tailgate brake lights.

Since three brake lights all stop work, I should check three things:

1: fuse 7
2:brake switch switch broken.
3:BFS fail

First, I check the fuse 7, it is ok.
The BFS is ok too. See the pic below. The first owner have alraedy by-pass the BFS by connected termiall 9,10,11 directly.




So, the only remaining one is the brake light switch.

After I loosen the two 12 mm nuts(circled number 2), it still there. So, I found it was tighten in the brake bracket . After several time try, I have no clue how to take it off.

Any one have experienced to take it out and replace it? How to take it out easily?

Thanks.
