I'd double-check that bulb. The turn signal and brake light use the same filament (in the dual-filament bulb), so I'd be willing to bet it's looking good when it's really not. Hook up a multimeter to it and check for continuity across the filament, or replace it with a known good bulb.

If the bulb does check out, then make sure the bulb socket is clean, and then start following that wire up to see where it's broken.

also on this model the light housing is the ground. Double check your grounds if all else checks out. you may need to tighten the big screws holding the housing in.

Do all the above, then try doing it again. Then make sure all contacts on housing are clean. Remove tail light housing and clean all metal to metal locations to ensure good ground. If emergency flasher works and blinkers don't after cleaning everything, then look at your turn signal switch.
