I was driving my 1990 1500 silverado, when I hit a bump and it sounded like something fell of. I pulled over and looked but nothing fell. I checked the blinkers and they would both flash when turning right or left. They where both working before. I checked the ground wire and it was still connected. I just dont kinow at this point.
check for the blinker relay. It may of fallen off so without a relay both blinkers will flash.
