Since the days of pulling a DRL fuse are gone, I had to get a little inventive. Ordered a new headlight switch from GMPartsDirect for $26 to play with. The goal was to be able to manipulate the switch so it could stay in the "off" position rather than always springing back to "auto" so I could leave it "off" and not have to turn it every time I got in the truck.
(Don't judge the dirtiness of my truck. I work in a rock quarry lol)
Removing the factory switch is a pain. First you'll need a 7mm socket to take two screws out of the lower dash trim.
Then pull on the top corner of the trim piece closest to the steering wheel. It's held in by a few trim tabs. You'll only be able to pull it 1/2 way out due to the hood latch release still being attached to the bottom. You'll see a tab on each side holding the switch in place. Pull the tabs outward and disconnect the wiring plug.
Taking the switch apart is pretty self explanatory. Four tabs hold it together. Use a small flathead to push tabs and pull the housing apart. Had to pry a good bit but nothing broke.
Once apart, you'll see the spring in the upper corner. You'll also see this flat little metal piece. Take note of where the metal piece sits. Very crucial that it goes back in the same way. Spring is circled red. Metal piece is circled green.
Remove spring. It will not be used again. Make sure flat metal piece goes back into its little slots that it came out of. Your fingers will get covered in grease during this. They went a little crazy when applying the electrical grease to everything. Now put it all back together. Make sure the electrical pins for the plug fit back through. It is a hair tricky making the knob go back through the hole. That flat metal piece kinda catches the side of the knob. Just wiggle everything until it all slides back together. Put the back plate on and you're all set.
Once this modification is done, your truck will always get an off signal if the switch is left off. The only downside is your headlights won't turn on when you unlock the truck, if that's how you have your unlock sequence set. That's a perfectly fine trade off for me. Tired of turning the headlight dial off every time I get in my truck.
Thanks for reading and post any helpful comments (except "why would you do this?")
