I've been having some issues with the low beams not wanting to work intermittently on my '06 GP GT. Bought the car a little over 2 years ago and the problem has been happening since a few months after I bought it, but lately has gotten worse. They go off with no warning and come back on anywhere from 5 minutes to an hour down the road. Fog lights, high beams, and tail lights all work fine. I have no idea what the problem is. Sometimes I go for an hour drive and they're fine, sometimes they quit working 5-10 minutes after I start driving and don't come back on until much later. I've read online that apparently many people have these kinds of problems with their 04+ Grand Prix's, does anyone know what could be wrong?
