Right rear blinker not working on 2007 Ford Fusion

I replaced the right rear blinker bulb and socket. The light works now, but the blinker is not. I don't know what else it could be.

Asked by for the 2007 Ford Fusion
Is it the correct bulb? try swapping the bulb from the other side and see if it works or does the blinkers not work on either side?
