Pulling up on the brake pedal turns them off. Sounds like a bad stop light switch. It's attached to the back of the brake pedal. Sincerely, James Daugherty TidBits Summers here. Check your battery.
Batteries seem to fail more in hot weather.
Be sure and check your radiator and coolant level and change your oil. Check the inflation on your tires. Check the air pressure when tires are cold and adjust then because high temperatures cause the air pressure to expand. Check the hoses because hotter temperature makes the rubber softer and more prone to failing. This may help on your trips this summer to keep you out of trouble.
