Bulb Replacement & Truck DNA

So all videos I have seen thus far to replace the bulbs on 3rd Gen models I need to remove the grille and the panel below the headlight. Is this 100% the case?

I ask cause my Silverado I had some vendors told us to remove the bumper corners and I was able to do w/o that.

Any luck?

Also i just got the truck ('16 used) and there is a box in the glove box called Truck DNA....what is this?

 

@Mootball if you’re going to replace the headlight bulbs you def have to remove the grille. Ask me how I know. If you’re just doing the turn signals and you have smaller hands you can probably change those out w/o removing the grille.

I don’t know what DNA is. Sorry

 

You can get at it via the mud liner, but it's a giant PIA compared to taking the grill off.

 

Taking off the grill is not as scary or difficult as it seems. The bulbs are a very easy job. Use ole Gunny Google and YouTube and it will put your mind at ease.

Yeah jts not that hard to pull grille off to replace HL bulb or any bulb in the HL housing, the grille is 4 bolts and 2 plastic push align pins take out a simple pull up from top the slight up in out tug from grille then the two plastic pieces below HL ther are 2 plastic align push pins pull those covers from the align pins towards you and pull back 3 bolts holding HL housing (someone correct me if I'm wrong)

 

Close enough! It’s not hard at all. I’d recommend getting a few extra push clips in case you break a few.
