The other day I was driving and everything was fine. When I went to get out of the car my automatic locks wouldn't work. Then when I went to leave again my, interior lights, headlights, rear windshield wiper and the lights that indicates whether I am in 4WD drive or not stopped working. I have tried switching the fuses but it doesn't seem to fix any of the problems. Does anyone know what the problem may be and how to fix it?
