First picture is the entire drivers door module. It has door lock unlock window lock windows up down for 4 doors 3 buttons for changing mirrors and 2 buttons for folding the mirror. On the left side of the first picture is the wiring harness for the issue. The second picture the red/white on bottom left is the wire that has no power going to it. If you hook power to it the entire unit works windows locks mirrors everything without it none works. I put a test light to both of those red/white wires and one has power but one doesn't. I'm also wondering why there is 2 red/white wires going into this unit. I switched the circuit breakers around and nothing happened. While I had the truck started I also realized it definitely isn't the DDM because the heated seat switches don't work either unless the power goes from the DDM to power the heated seats switch. I also have a carsoft code reader it wont connect to the DDM but it connects to the passenger door module and it gives code u0199 cannot connect to DDM.
