Its AUTOMATIC...Bill Gisse said:Haven't figured out to turn my day time running lights on. The dim night time lights come on t instead. have 2003 GMC. Anybody know the routine for turning them on. The ones in my book don't work. Thanks.

Bill Gisse, it sounds like you have a faulty light sensor. The truck thinks that it is dark out so it turns the headlights on as soon as you start the truck.
I never knew if my lights were working or not either... I kept playing w/the dial like a fool, not really knowing what i was doing...But that explains it perfectly....Thats also the light setup on 03 chevys to...NoWake200 said:On the 04s you can turn the DRLs on and off. But like everyone said the truck must be out of park or in gear PB off. On the 04s there are four settings for the lights....On, Parking, Auto, and spring loaded off that is marked with a circle.
Once the switch has been turned to the circle, long as the truck is not turned off they will remain off all that time....even going in and out of gear. Once the truck is shut down it will reset.
army said:The button next to the headlight switch turns off your interior light door switches so the truck stays dark when you open the door. Canadian DRL's are the same as US. The only differance on the two systems is that the Canadian trucks can't have they're headlights turned off by the manual light switch at night. The light sensor theory and/or stuff on the dash covering it up is what to look for.
