It’s taken me a few day to troubleshoot that the door power lock problem was due to a bad door lock actuator. I had replaced the automatic lock relay first thinking that if all doors failed it must be a common component between all four door (crew cab). It turned out to be the actuator itself. I disconnected the push lock rods and tested the original actuator itself and the plunger barely pushed out and retracted. The voltage going to the actuator was +12V constant. I could tell the actuator was the original part since the two mounting rivets were still in tact.
