Last week I noticed when driving into the garage, that one of my DRL/low beam lights was out. I have a 2015 with the halogen lights, separate high beams. I first read some old posts on here about how to get at them. No problem, I bought a new set of H11 bulbs and went to replace them. I put the new bulb in the driver's side first since it is easier, the new bulb worked. (that old bulb still worked as well). Then I go yank the air box out to get at the passenger side. put new bulb in. After reassembling everything I tested it out by turning on my headlights, and lo and behold, this brand new bulb does not light up. After inspecting the old bulb, I cannot see any sign of it burning out either, no black, nothing broken inside the glass. So my question is, would there be anything I can easily check that would cause this if it is a wiring issue? I'm not terribly worried about it now since I do very little driving after dark and I will be taking my truck in for an inspection right before my 36 month warranty runs out in June. Just wondering if this has been encountered before. I don't want to make a habit of replacing bulbs only to find out they are not the problem. Replacing the passenger side bulb is not fun.
Low beam and high beams randomly stopped working other day on my 2015 Sierra 1500. All the grounds and fuses have been tested for power and they are all fine. All my other lights including parking, turn signals, taillights, hazards and fog lights work fine. Could it be the BCM or am I missing a fuse panel or ground?
