2011 GMC Yukon- when switching to
highbeams my headlights shut off,
along with my fog lights (when I have
them on) the parking lights and
taillights stay on. When I switch back
to low beams, the headlights turn back
on. Any suggestions??
The fog lights will only operate with the low beam headlights or when you have just the parking lights on. That's normal. For the high beams not working, check the bulbs first. If you have daytime running lights do they work? If not, the bulbs are suspect. On my 03 S 10 Pick Up if one high beam bulb burns out the other one goes out as well. Hope that helps! Jim
