(1) Auto seatbelt has worked on and off lately. Then today, it stopped working. Everytime I had this problem, the warning light (seatbelt) was on and the buzzer beeped until I turn off the starter. What should I have to look up? Will the repair cost a lot? (2) When I turn on the headlights, the lights in the dashboard will be turned on in 10 seconds or so. I'm worried if they'll be gone sometime soon. What should be checked?
