Rear Door Electric Lock Failure

I have a 2005 SR5 V6 Tacoma and a few months ago the driver's side rear door lock quit working both with the Fob and with the control panel in the truck. Now the passenger side lock has quit working as well. There is no noise or movement in the lock when I hit the unlock buttons. With it working its way around the truck I want to find the solution before it works its way around to the front doors!

I've found a few posts with similar products, but I have not been able to find any solutions to this issue. Does anyone have any ideas of how to take care of this? I have already taken apart the door to check the wires/connections and everything seems good to me. I have noticed in other posts that the child lock is a part of the discussion, but the child locks do not control the locking mechanism.

Thank you for any help you can offer!
