Passenger Window Control Switch - With Memory Driver Seat

The PDM provides a return (ground) for the passenger door window control switch. The passenger window control switch sends 2 separate signals to the PDM: up and down. When the window control switch is pressed to the first detent position, a ground signal is sent to the PDM to request an up or down operation. When auto up or auto down is requested (switch activated to the second detent position), the window control switch provides a ground signal on both the up and down line simultaneously. During an auto up or auto down request, the PDM determines intended window direction by the signal first received
