A time division multiplex system includes pulse width modulation to provide an automobile interrogate and control system whereby either the driver or front seat passenger can manually-operate switches mounted on doors to control door locks, windows and seat positioners. The system includes a transmitter module located in the left front door which transmits information to receiver modules interconnected by a data line and located in the passenger doors and under the front seat. The receiver in the right front door is capable of modifying the information received from the transmitter and placing the modified data on the data line to permit control of the right seat adjuster and all of the vehicle doors from the control located in the right front door. Stall of window motors or door lock solenoids is avoided through priority logic.
