If the high mount brake light is working I recommend you have the turn/hazard flasher module-the bottom lights circuits goes thru this module also could be open on splice S-406

Check fuse, then for power through the brake light switch. Then it goes through the turn signal switch
before shootin to the back. U can test all this with a test light or multimeter. I say its the turn sigal, plug the new one to test proper operation before installing hope this helps
