OK,,,,If you want to shut off the DRL's just pull the fuse. If it's the headlights and parking lights you are talking about your ambient light sensor in the middle of the dash isn't working right or is covered with something? In mine I push dome light button four times to disable automatic headlights and running lights, it's a 02 Chevy. Hope this helps you.
It works only untill you shut down, then it resets with the next startup. At least thats the way it is with my 02.OK,,,,
1. Do I need to do this everytime I get in the truck or is there a way to make it permanent?.....
2. Will it work if the headlights are already on?
