Headlights on 2003 Chevy Express won't turn off, why?
Headlights on 2003 Chevy Express van won't turn off and they will sometimes turn themselves on, even when van is not running. Clicking noise is heard also.
The twilightsentinal on the van ahs gone wacky ...might just be the outside light sensor but you should be able to pull relay or fuse and disable system
