Tundra Door Lock Problems

I have a 2007 Tundra and am experiencing door lock issues. The locks work on some of the doors sometimes, with either the remote or the door switch. I have tried to do some research but everything keeps pointing me back to the actuators. If it is the actuators, I would think it would be isolated to one or two doors. But it seems to happen with all of them. Sometimes they all unlock/lock. Most of the time they don't. The right rear door works correctly most of the time, but the others not so much. I find it hard to believe that all the actuators would go out at one time.
