I have checked the obvious connectors and where bulbs are plugged in. the fuse DOES NOT blow when I just turn on the lights. But when the car is running, or if I start the car with the headlights already on, then it blows immediately. If I just leave the lights on, the tail lights and instrument panels light up fine and stay on, but as soon as the car is on at the same timem - it blows. I have looked for hours. Any suggestions? I have read other posts about checking the ground, but not sure where or what to check.... Thanks!
