My right rear turn signal won't work even after replacing bulb...?

Hello, is the light socket getting power and does it have a sufficient ground? The bulb -- making sure you are using the correct one for the application - is the first obvious thing to try, but not the only possible cause of the problem. For example, you may have to trace the wiring harness if there's an interruption in power or ground.
