My cruise control turns on and off as it should. The problem is that the set and resume functions don't work at all. I couldn't find a fuse that is associated with cruise control. It is the basic cruise control as well, NOT the adaptive cruise control. Any tips would be appreciated.

I have 2015 Sierra. One night my lights were barley bright enough to drive. Both sides are dim. The high/ low shutter function seems to be working. All of my other lights / electronics work. No change if they turn on auto or manual . Any suggestions???
