I'm having a little problem with my turn signals.

The left side signal works just fine. The bottom housing on the bumper has a bad bulb so it's a little fast but works fine. The right signal doesn't work at all, but when I push the hazard button both sides light up just like they should. I thought this was the signal switch, so I replaced it but the problem still persists.

Is there a common failure with this system? Also, how would I go about troubleshooting the problem.

 

Changed flasher relay, no change.

and bump.
