SYSTEM DESCRIPTION

1. POWER WINDOW CONTROL SYSTEM DESCRIPTION The power window control system controls the power window UP / DOWN function using the regulator motors. 3 Door: The main controls of this system are: the power window regulator master switch, which is built into the driver side door, and the power window regulator switch, which is built into the passenger side door. Pressing the regulator switch or either of the switches on the master switch transmits an UP / DOWN signal to the corresponding power window regulator motor. Except 3 door: The main controls of this system are: the power window regulator master switch, which is built into the driver side door, and the power window regulator switches, which are built into the passenger side door and rear doors. Pressing the regulator switch or any of the switches on the master switch transmits an UP / DOWN signal to the corresponding power window regulator motor.
2. FUNCTION OF MAIN COMPONENT Component Outline Power Window Regulator Master Switch Assembly Controls window operations for all windows When window lock switch is set to lock position, window operation is only possible with master switch Power Window Regulator Switch Assembly 3 Door: Located on passenger side door Except 3 door: Located on passenger side door and rear doors Each regulator switch controls window operations for its respective window Power Window Regulator Motor Assembly Receives switch signals and changes signals into motor activation to change window position
3. SYSTEM FUNCTION The power window control system has the following functions. Function Outline Manual UP / DOWN function Driver side power window: Function that raises window while power window switch is pulled up, and lowers window while pushed halfway down (window stops as soon as switch is released) Other power windows: Function that raises window while power window switch is pulled up, and lowers window while pushed down (window stops as soon as switch is released) AUTO DOWN function Function that enables window of driver side door to be fully opened by one full push downward on power window switch Remote UP / DOWN function 3 Door: Function that allows power window master switch to control manual UP / DOWN operation of passenger side power window Except 3 door: Function that allows power window master switch to control manual UP / DOWN operation of passenger side power window and rear power windows Window lock function 3 Door: Function where passenger side power window operation is disabled when window lock switch of master switch is pressed Passenger side power window can be operated when window lock switch is pressed again Except 3 door: Function where passenger side power window and rear power window operation is disabled when window lock switch of master switch is pressed Passenger side power window and rear power windows can be operated when window lock switch is pressed again

DESCRIPTION

3 Door

With the ignition switch ON, the power window regulator master switch transmits remote switch signals to the regulator switch of the passenger door power window. Then, the regulator switch drives the passenger power window regulator motor.

Except 3 door

With the ignition switch ON, the power window regulator master switch transmits remote switch signals to the regulator switches of the passenger door power window and rear door power windows. Then, each regulator switch drives its respective power window regulator motor.

Scheme 9

If the manual UP / DOWN and AUTO DOWN functions do not operate, a malfunction may exist in the power window regulator master switch, power window regulator motor or wire harness.
