Here is the description and operation of the Door locks. This is much different than the operation of the locks in the 92-99
The vehicle is equipped with power door locks. Each door lock actuator is powered and controlled by the door module mounted in the individual door. The driver door module (DDM) is the master control for the door lock system but the rear integration module (RIM) determines when the lock functions are permitted.
The front passenger door interior lock switch is wired to the front passenger door module (PDM) while the driver door interior lock switch is wired to the driver door switch assembly (DDSA). Interior lock switches are not provided for the rear doors. The DDSA and the PDM send the lock switch requests to the DDM over the power door serial data circuit. The DDM then sends the lock requests to the RIM over the Class 2 serial data circuits.
The lock operation modes are controlled by the RIM. The RIM examines the lock and unlock requests from the DDM, or the remote function actuator (RFA). The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the DDM commanding the DDM to perform that function. The DDM then locks or unlocks the driver door and sends commands to the rest of the door modules, via the power door serial data circuit, to lock or unlock their respective doors.
and here is the window description and operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally to its associated door. The driver door window can be operated only from the driver door window switch built into the DDSA.
When a window is operated from the DDSA, the DDSA interprets the window switch signal as a specific window switch request and sends the information to the driver door module (DDM) via the power door serial data circuit. The DDM examines the request and checks to see if it has received any class 2 serial data messages from any of the other vehicle modules (i.e. ignition switch position) prohibiting the movement of the window. If the window being operated is the driver door window, and if no prohibitive class 2 messages have been received, the DDM then applies voltage and ground to the driver door window motor to move the window glass as requested. If the window being operated is a passenger door window, and no prohibitive class 2 messages have been received, the DDM sends the request, via the power door serial data circuit, to the appropriate passenger door module. The passenger door module then applies voltage and ground to the passenger door window motor to move the window glass as requested.
When a passenger door window is operated from the power window switch mounted locally to its associated door, the passenger door module first checks to see if the DDM has received any prohibitive class 2 serial data messages. If there are no prohibitive messages, the passenger door module powers the associated passenger door window motor.
so it sounds like the DDM might be faulty in this case. please let the other 00+ guys take a look at this/reply as well before taking any action
