2017 Sierra Tow Mirror Problems

[MagicDragon252]

I recently bought a 2017 Sierra 1500 which had the tow mirrors already installed. I didn’t notice until a couple days later the running lights on the tow mirrors turn off as soon as the truck goes in drive. They work in park and  the turn signal work. Does anyone know how I came make them stay on when the truck goes into drive as well
