OPERATION

WINDOW SWITCH

The Driver Door Module (DDM) or Passenger Door Module (PDM) control the battery and ground feeds to the power window motors. The driver and front passenger door power window switches are integral to the DDM or PDM. The rear passenger switches are inputs to the DDM or PDM. When the power window lockout switch is depressed it will toggle between window lockout enabled (illuminated red) and window lockout disabled (illuminated emerald green). When the window lockout is enabled, the switch illuminates red and extinguishes the illumination in the passenger window lift switches indicating that they are disabled and will not activate their corresponding window. When window lockout is enabled the DDM will still be able to actuate all of the windows. When the window lockout is disabled, the window lockout switch will illuminate emerald green and again allow the passenger window lift switches to activate their corresponding window and return illumination to the passenger window switches.

WINDOW MOTOR

Window motors use permanent type magnets. The B+ and ground applied at the motor terminal pins will cause the motor to rotate in one direction. Reversing current through the motor terminals will cause the motor to rotate in the opposite direction.
