the right turn signals do not work. there is no power to the turn signal/hazard switch for the right side. confirmed with test light. There is power to left turn signal, hazards, stop, and taillights. All bulbs are fine and work. fuses are okay but no power to right turn signal from front to back.

These system get their power from the BCM which has fuse: RT STOP/TRN which is located in the fuse panel at the left side of the fuse panel. Here is a guide to help and the location of the fuse in the images below.

Okay good, and bad, lol. It looks like the BCM has gone bad as you can see from this wiring diagrams the BCM is what supplies power to the switch. You might want to try unplugging the BCM and plugging it in again, this can sometimes work. Also, I would try a hard reboot which this guide can show you how.

If these don't work then a CAN scan can help confirm the failure, please watch this video:

Here is the location of the BCM which you can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Let us know what you find.
