I'm sure a similar thread is buried deep in the archives but I can't find it anywhere. All I see is guides about 00-02 trucks but they changed the interior in '03. I need to find out how to disable automatic headlamps completely in my 2004 Yukon. Basically I want to fool the truck into thinking its always daytime, so I want my DRLs to run unless I physically turn the knob to bumper signals or lowbeams. Thanks.
