98 chevy malibu brake light doesn't light up?

[Mercury 2010]

so, if I turn on the lights, the back lights light up, but when I put it in reverse, I don't get a reverse light on the right side, AND when I put on my brakes, the brake light doesn't get BRIGHTER...... my lights work, but I'm missing the reverse trigger and brake trigger.................

what should I replace?

so, I checked all my fuses..... no luck
I've cycled all 4 bulbs in the back right light casing. ALL 4 seem to work and light up.

I've already replaced the brake light fuse.
(it popped in the middle of me testing the lights... when it was popped, nothing worked
I'd suspect wiring too, but the light housing did hold moisture for some time, I'm thinking its the bulb board, but I'm not aware of circuits or fuses in the light housing.

As far as the brake lights, Check the brake light fuse.
If you have one reverse light you'll need a bulb for the other side.

BRILLIANT!!!!

you should check your wiring
