the Headlights on my 2006 Cobalt will not come on what could be the problem.

Do the park lights, tail lights etc. come on? If so I would suspect the headlight bulbs. Is it possible they are both burned out? It seems unlikely, but it could happen. Try turning them on and then switching from high beam to low beam. If they activate on one or the other setting I'd think its the bulbs.

Park lights, tail lights come on. No high beam. It's not the bulbs or the switch as we bought one and put it in.

My Cobalt just developed the same issue. Did you ever get your problem resolved?

Same problem and it's dark and no front blinkers. Fiddled with them before when this happened and worked but now it won't turn on at all.

I got the same problem headlights won't come on high beam low beam works can't figure it out

Matthew, you might want to start a new thread with your question. Not many people will see it on an old thread like this one.
