Rear brake lights, turn signals, and back up lights not working
I have a '98 Chevy Silverado K1500 that's having rear light issues. The brake lights, turn signals, and back up lights stopped working. It doesn't matter if the lights are on or off. However, when I turn the lights on, my tail lights come on and stay on until I turn them off. My third brake light is also working regardless of the lights being on our off. I have checked the fuses under the dash and the few under the hood as well as replaced all the rear bulbs with no improvement. Any ideas, suggestions, or solutions?
