Turn signal not making noise?

By default, the turn signal indicator signal is on and cannot be turned off. I would try to disconnect the battery overnight and then reconnect the battery to help the system reboot and it could come back. The blinker noise is generated by the BCM which if the reboot does not work will need to be replaced. Here is the location of the BCM and how to replace it in the images below. You can get a rebuilt BCM by searching google or eBay. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
