Sorry for it taking so long to get back with you. My son has a voltage meter and is going to stop by in the morning. This is how the lights are working/not working: The tail brake lights don't come on at all. When I turn on the head lights, the tail brake light bulbs come on so I know they work, but; when you press on the brake pedal, the brake lights don't brighten; although the one in the center of the back window above the trunk works fine. All the other lights on the car work the way they are supposed to. I checked the fuses inside the car and in the engine compartment and they all appear to be fine. Once I have a voltage meter, where should I start? I've never used one but my son says he knows how to use it.
