My cruise control was working perfectly fine earlier in the day, but tonight when I tried to set it, I realized the lights that are usually on at night were all on but the lights on all the cruise control and the up and down and ok/reset buttons lights were all off on my right side of my steering wheel and i couldn't set the speed no matter what but the light when i turned cruise control on (the cruise control main)_still came up on my dashboard. I don't wanna go to the dealer without knowing what exactly I can troubleshoot at home. Does anybody know what I can do?

Edit: forgot to say that the car wont beep when i double click the lock button either, and it was just doing it earlier in the day
