DRLs only when lock/unlock

DRLs only when lock/unlock

Postby ThomasInVancouver [OP] » May 04 2021, 12:41am

2007 Classic 2500, Canadian truck
DRLs only illuminate when the truck is locked or unlocked. Headlights come on when I take off the parking brake and only turn off when the ignition is off. They don’t turn off using the headlight switch, but they do turn on. Is this something that is broken, programmed into the vehicle but reversible/changeable, or is it a Canadian thing and I just have to live with it?

I believe that is a Canadian thing. Hard programmed into the BCM and is unchangeable, I think.

I also have Canadian made truck. My DRL's some on anytime the vehicle is taken out of Park. Headlight switch can be rotated counter-clockwise, and headlights should go off. Headlight switch default position is on 'auto'.
