When I Start car the headlights do not automatically come on and there are no rear or interior dash lights. Also when car is off lights are turned off and he is out of ignition and I open the driver side door the car dings like something has been left on but it hasn't. When car is running or off I can manually turn on headlights and they work but I still have no rear lights or interior dash lights. All other rear lights work. This is a huge problem I need to fix it I am a Widow and don't have much money so I need to fix this on my own can you help me?
