Dangerdick: first of all, love the name. Second, If I want to disable DRLs, the dealers should offer the service of disabling said DRLs for free or a small fee since there are no laws requiring automatic and DRL features.
Rick, you are missing the point. The lights should be off whenever I start my truck. The lights should remain off until I decide to turn them on. Dantheman, this has nothing to do with safety and everything to do with not liking having decisions made on my behalf without my consent, even if the issue is as simple as daytime running lights and automatic lights.
So, no one except for Chris White can disable the DRLs/automatic lights? it is total b.s. that Chevrolet service departments will not disable them via the BCM. The federal laws were changed in 1990 so that GM could sell vehicles in the U.S. with DRLs and automatic light features. There are no laws within U.S. borders stating we are required to have DRLs or automatic lights.
