Hello BrainPool- I have a 95 Chevy Diesel 2500 pickup yard truck. Over the last couple of days, I have lost, progressively, the headlights (high beams still work), the dash illumination, and now my rear brake/parking/backup/and license plate lights and turn signals. All the fuses are still good. Also, had a trailer hooked up today, and its turn signals and brake lights DID work. Can someone point me in a direction to get started solving this my self? This is a truck that is registered as AG and I don't want to put much into this. Thanks in advance!
