Driving home in my 03 Trailblazer 2wd with stock EVERYTHING including auto lamps the low beams just shut off. I was able to use the high beams with no problems after about a half mile the low beams started to work with no problem. This is the first time it has ever happened but i wantsee if anyone else has had this problem so i can repair this before it happens while i am further away from home. thanks for any help offered.
