Drivers Door Power Window Control

The drivers door power window switches are built right in to the Drivers Door Switch Assembly Module (DDSA). The DDSA provides control of all the power windows from the drivers position. This switch also has a lockout button, which the driver can use to prevent the other window switches from functioning. The DDSA passes the switching information to the driver door module, and to the other door modules by way of the Serial Data Class 2 line. Battery voltage and ground are applied to each doors power window motor by each doors module through the associated motor control circuits respectively.
