I recently bought a car from a private seller. The blinkers and emergency flashers don't work. Also, the radio and dome light used to work, but no longer do. I am trying to avoid going to a dealership or somewhere to get it fixed, and would rather do it myself. Any ideas on what it could be? It is not the fuses in any of the three fuse boxes. They have all been checked, and the few bad ones were replaced. I don't know much about cars, so if you can help, try to use terms I can understand
