My wife's truck is a 2012 LTZ and she called me last night saying her headlights wont turn on. None of the bulbs were out prior which leads me to think its a fuse or relay issue. This morning i replaced the lo beam relay (4 prong) but the one given to me by local Part Source is a 5 prong but it fits because the location did have a location for the 5 prong to fit. That didnt help. I replaced the 10 and 15 amp fuses for both headlights but that did help either.
Is it really possible that both headlight bulbs could go bad overnight at the same time?
Other than the bulbs what else could the issue here?
Any insight would be greatly appreciated.
