Are you talking about the automatic headlights? I had a '99 GV and have an '02 GV. The headlights are put on or off automatically by the position of the passenger interior light switch setting. IIRC, if the light switch (on the '99, it's in the back..on the '02 it's on the front of the light housing in the ceiling) is in the center position, the headlights on/off are automatic. If the switch is in any other position, they're manual and controlled by the position of the switch on the lever beside the streering wheel
