The automatic headlight switch only turned on the running lights but not the headlights, upon shutting off the vehicle the warning chime sounded, the running lights would not shut off. The only way the headlights will come on are to turn them on manually with the switch. This all came on suddenly with no warning. Is this just the switch malfunctioning or or is there a relay involved somewhere. The battery saving feature of shutting off the lights after eight minutes does not operate either.
