I have a 16 Sierra, the high beam headlights have stopped working, this happened after installing a cold air intake, fuses are good and the indicator light on the dash comes on, any ideas?
Yes I use the Range Technology AFM disabler , I recommend this to anyone that has a truck like ours, I tow my boat and camper with my truck and do a fair bit of highway driving, I love it worth the money! Fuel economy goes up too!
