does a 96 sierra sle come with daytime running lights? ive never had them on my 96, just on and off with the knob, but suddenly today i have them, while the key is on i can turn the lights off and everylight but the headlights turn off, and when i turn off my key they go off, then come on as soon as i turn the key again, i figured something electrical was going haywire, but i have a fuse for it in my fuse block
