headlights not working
I have a 2015 GMC SLT. The headlights have abruptly quit working, Daytime running lights and fog lamps still work. High beam are VERY dim when switching from low beam, that do not work at all. When trying to manually switch lights on you can hear a clicking noise.
Could be a defective dimmer switch or module. Less likely, would be a defective headlight switch.
Could also indicate a failing relay.
