OK. So I have an 2002 S60 T5 and both rear brake lights dont work.
The brake light in the window does though.
I tried replacing the bulbs, didnt fix it.
I looked at the fuse for the brake lights, looks fine.
Slammed trunk, bumped the wires a little bit, nothing.

I dont know what else to try.
Anyone help me please?

There is a relay that sometimes goes bad in the rear fuse/relay box.
I forget off hand which one. I have posted a diagram before of the relay box and what one is for what.
