Does your cruise control work properly? If its faulty maybe has something to do with the ON light???

na cruise control dnt work. its got me thinking tho y is the light on when the car is off n keys out of igniton. im finking for just pulling hte globe out for now. but the temp one still got me confussed. ive done new thermostat. but the temp light comes on n beeps even when the reds r on thats it. so thats why im thinking it could be an electrical fault
