gmc canyon all three lights work on tailight assembly but the tail light dont work.?

The top bulb is for tail light and brake light. The brake light works fine as does the other two bulbs in the assembly (turn signal and back-up light). But with the head lights on the tail light does not work. This is on the driver's side only. The passenger side works fine.

The tail-light filament is burnt out in that bulb or bad electrical connection with that circuit to the bulb. Spend the $.75 for the bulb try it, if that doesn't work, then come out here ask again. Please kids, sometimes it's cheaper to use common sense try something yourselves (you'll learn in the meantime), than to come out here bother the people who have real problems, like owning a foreign car..............LOL!
