With Automatic Down

System Description
The operation of the power windows is controlled by the main switch in the master power window switch. When the main switch is in OFF, only the driver's door window can be opened or closed. With the main switch ON, all windows can be opened or closed by either the master power window switch or the window switches in the doors. The driver's window switch has an automatic down mode which is turned on by pushing the switch down to its second position.

The power windows are driven by reversible motors. Each motor is protected by a built-in circuit breaker. If the window switch is held on too long (with the window obstructed, or after the window is fully up or down) the circuit breaker opens the circuit. The circuit breaker resets automatically as it cools.

When the ignition switch is in ON (II) (and for 10 minutes after it is switched to LOCK (0) and as long as both front doors remain closed), the integrated control unit provides voltage to the coil of the power window relay. The contacts of the power window relay close and voltage is applied to the master power window switch and all the window switches in the doors.

Automatic Down (Driver's Window)
With the ignition switch in ON (II) (and for 10 minutes after it is switched to LOCK (0) and as long as both front doors remain closed), voltage is applied to the coil of the power window relay by the integrated control unit. The contacts of the power window relay close, applying voltage to the driver's power window switch. When you push the driver's power window switch to the AUTO DOWN position, voltage is applied through the driver's switch to the power window motor. The control unit receives pulses at the pulser input while the motor is operating. When the window is fully down, the motor stops and pulses are no longer generated by the pulser. This is sensed by the control unit (at the pulser input terminal), and voltage is no longer applied to the power window motor.
