Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Driver Door Module (DDM)
The DDM (if equipped), is located behind the LH front door panel. It controls the memory functions of the exterior driver memory mirror and, in conjunction with the Driver Seat Module (DSM) (located under the driver seat), indirectly controls the memory seat functions. The DDM also controls the lock and unlock functions of the driver door lock actuator on vehicles with memory (seats and mirror) and receives lock/unlock input information from the door lock key cylinder switch and reset information from the driver door lock actuator.
