Hello my name is ***** ***** I'll be happy to help you today, I apologize for the delay, there are two power wires, one is a circuit breaker #2 and a fuse named DDM which is fuse #10 they are in the fuse block under the left rear seat, if you already check power and grounds those two wires have power and the ground is good, the next step would be check the data communication in the drives door module, is there a way you can connect a scan tool and be able to communicate with the drivers door module? If it has good power and ground and the data line is open or shorted the module won't work, check the wiring harness by the black grommet that is by the door hinges sometime with the opening and closing of the door some wires can break causing an open
