I have a 96 Chevy Silverado k1500. I just replaced the rear brake line due to a hole wearing in it. After bleeding the brakes, I noticed that my brake lights were no longer working. I checked the bulbs and fuses. They are both good. Thought that the stop lamp switch might have been damaged while the brakes were being pumped up so I replaced that, but that didn't solve the problem. Checked the wiring harness and didn't notice any damage. I'm at a standstill as I don't know what to check next. Any suggestions?
