My driver side brake lights are not working. I replaced the bulbs, but it still doesn't work. The passenger side works fine. What could be the issue with this.
Brake Light not working on 2003 Toyota Highlander
More than likely, its the bulb socket and/or the 'pigtail' (wiring loom) attached to that bulb socket.

On the bulb housing there are 3 prongs most likely there is a loose prong next to the light.... find that one and bend the part closest to the light slightly away from the light being sure to keep the 90 degree and that already exist. You're basically grabbing the lip and pulling it out a little.
wiggle the harness.
