The ones in the front work but the indicators on the dash don't work either. I have checked the fuses and they are fine. Are there any relays within the fuse box that could cause this problem? I have researched a bit and it seems that it would be the flasher relay. But as I research more I'm hearing/seeing that there isn't a flasher relay and the body control module is responsible for the flashers.

Good afternoon,

Make sure there is power on both sides of the fuse for the rear lights as in the diagram.

I attached a diagram for you. The power is controlled by both the body control module and the turn signal switch.
