I was told my passenger side taillight was out. I brought a new bulb and it still didn't work. Then I noticed the brake light wasn't working either. Only on the passenger side. Driver side works. Only the turn signal working on both sides. Can someone tell me what's the problem?

Hello,

This is common when the light failure module goes out by the left rear trunk pillar by the rear seat. Here is a guide to help test through the module and the wiring diagrams so you can see how the system works:

Check out the diagrams (below). Please let us know what happens.
