Power Windows Operation
The vehicle is equipped with power windows controlled by door modules. The passenger door window can be operated, either from a power window switch built into the driver door switch assembly (DDSA), or from a power window switch mounted locally on the passenger door. The driver door window can be operated only from the driver door power window switch built into the DDSA.
When the driver door module (DDM) receives a driver door window switch request from the DDSA, the DDM examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the DDM will apply power and ground to the driver door window motor to move the window as requested.
When the passenger door module (PDM) receives a window switch request from either the DDSA or the window switch mounted locally to it, the PDM will examine the request and check for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the door module will apply power and ground to its associated window motor to move the window as requested.
