hi what is wrong with my car? Last night when I was driving it the radio just turned off, then when waiting at the light my car lights and dashboard clock began to dim and turn off and then when I pulled over and turned off my car it wouldnt start up again, but then after waiting for a while I could turn the radio on but when I turned my lights at the same time on they worked but the radio shuts off once something else is being used like windows or when I press the brake. But the car still wont turn on. I have people saying its a bad battery, some saying it's electrical. Can you help me?
