The right front, the left rear or the right rear windows are operational by using either the left front side master window switch (1) or the individual switch on each door. The left front side master window switch (1) also contains circuitry for the AUTO DOWN and WINDOW LOCK features. The AUTO DOWN feature allows the left front window to open automatically to the fully open position. The WINDOW LOCK feature allows the right front, left rear and right rear windows to be locked out. When you depress the window lock switch, operation of the right front, left rear or right rear is not possible through any window switch.
