I went out to start my bronco the other aftenoon, and nothing. Hooked a jump box to it and nothing. With jumber cables hooked to my other vehicle it just bairley rolled over. My first thought was the starter had gone bad, but I pulled it yesterday afternoon and took it to the auto parts store and they did a check on it and said it works fine. I also started seeing some problems about a week ago with my turn signals not working all the time and heater fan working part of the time also. Any ideas? Could the problem possibly be the ignition swithch?
