So all of a sudden my right turn signal died. As in no lights (front, mirror or tail), no green indicator on dash, no sound. Left turn signal works fine. Push button for hazard lights, then green indicator on dash lights up, and all the bulbs are flashing like they should. Fuse is good, even replaced to make certain. So thought it was multi function switch/lever on steering column. Replaced that but still nothing. What am I missing here.

In case anyone comes across this, and has a similar issue, for me the resolution was replacing the BCM. Which was about $140 on Amazon for new Acdelco, then $100 for dealer to program it.
