Thanks Jimmy, I swapped out a relay from a component that was working and that solved the problem. The relay for the brake lights was a different color, I'm assuming it was replaced before. Wondering if there is something else going on that required that relay to be replaced now 2 times.

2003 XC90 brake lights won't work but the third upper light does. The brake light switch appears to be working because I can shift out of park. All fuses are good and I installed new bulbs. Any suggestions?
