Hello,

This is more than likely going to be a bad taillight tail/stop and turn signal bulb. They are all incorporated into one bulb, so just because the taillight still works it doesn't mean that the bulb is still good. In the diagrams down below I have included the exterior lighting wire diagrams for your vehicle as well as the instructions for the removal and installation of the tail/stop and turn signal bulb for your vehicle. Please go through these guides and get back to us with how everything turns out.

Thanks,
Alex
