I have a 2010 sierra and the drivers headlight doesn't work, low/high beam...but the other light does, I've checked the bulbs and the fuses and everything it's good. Any help or suggestions?
Wiring. Start at the plug for the build and work your way back.
The headlight outlet is bad. The wiring has gotten hot. Look at the plug and the terminals. About positive you will find the problem there. I had the same problem on my Sierra. Just depends how much you run your lights.
Bulb not build. Sorry for the typo
