I recently purchased a 2008 Silverado 1500 and, shortly after, the driver side turn signal stopped working altogether. The turn signal blubs don't blink, the dash lights and chime won't activate either. I checked the hazard lights, and everything seems to be working just fine. All the bulbs and corresponding dash lights light up too. I assumed it was the turn signal switch and after installing the new one the problem still persists. I recently installed a new junction block, so all the fuses and relays are fine. I don't know if it's a bcm or connection issue at this point. If anyone has any suggestions or experience with this issue, I would greatly appreciate some advice.
