Turn on the fogs. Then save your settings using the 'memory seat' procedure.
Works on my Tahoe LTZ. Might work on your GMC . . . but then you never know . . .

Isn't it illegal in at least some states to use fog lights when the weather is not inclement? I doubt anyone enforces it, but fog lights are annoying to oncoming drivers.
