Intermittent Headlight

[akkeith]

I've been having an issue with drivers side headlight working intermittently. Sometimes when I start the truck it will work sometimes it wont and if I cycle the headlight switch it may start working. The truck is a 15 GMC Sierra 2500HD Denali. 

Thanks for any help.

 I had a intermittent light problem, too, and the issue was that I had tapped into some of the wires under the dash that connect to the body control module. I was doing that when I was wiring up my tow mirrors. In the process, the connection for the wire that controls one of the headlights was compromised. Fixed that, problem solved.
