Driver Door Module (DDM)

The DDM (if equipped), is located under the LH front door panel. It works to control 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. It also controls the lock and unlock functions of the driver door lock actuator on vehicles with memory and receives lock/unlock input information from the door lock key cylinder switch and reset information from the driver door lock actuator.
