My sons 2000 Camry stopped shifting, no brake lights and no cruise control. I changed out the brake light switch, but it still does not work? Any ideas, please. Thanks

Could be a fuse.
Won't shift until brake circuit fixed.
Remove Brake switch, jump 2 contacts(some have more), if it lights, switch is the problem and needs to be adjusted or replaced.
If it doesn't light, you need to see why you have no power to one side of brake switch.
