Lighting and Turn Signal Switch Inspection
WARNING: This page is about a different car, the 2010 Suzuki Kizashi. However, it is still accessible from the selected car via links, so may be relevant.
Reference: LIGHTING AND TURN SIGNAL SWITCH REMOVAL AND INSTALLATION
Check continuity between terminals at each switch position. If check result is not as specified, replace switch.
NOTE:
Dimmer/Passing switch does not have dead point. (Both high and low beam lights light up simultaneously at transition point.)
