My front passenger headlight is out, it was on then off then on then off again.

sounds like wiring issues inside loom

i had the same problem and it was the filament in the bulb you just cant see the separation on the filament

I suggest replacing the bulb as it could be the filament. Otherwise there is a recall on Aveo models of this year , check with the dealer to find out the status of the recall and your vehicle , keep records and do not let them hold you up for a bag of cash.
