Brake light problem
I have a 1987 Monte Carlo adn I'm having an issue with the brake lights. When you turn the headlights on, the brake lights come on except for the third brake light. When you push the brake with the lights on, the third brake light comes on. So the two taillight brake lights are always on. Also, if the headlights are not on, when you push the brake, the parking lights come on. Any ideas on this problem?
