no right rear turn signal

[BB'S 91'NOTCH]

My right rear turn signal stopped working the other day,i changed the bulb and socket and it still doesn't work.Could not find anything wrong with wiring and all the other lights and signals still work.Any suggestions?

use a test light and make sure you are getting power to the socket, Grounds are a good place to start as well.
