Dodge Avenger left headlight not working (replaced bulb and nothing)

check your fuses and power going to your headlight connector.

2009 Avenger, my experience, right headlight not working. I found that many black wires of the headlight wire harness were going into the wheel well protected by the wheel well plastic shields. Checked bulb power and ground and found the ground bad on all bulbs (some intermittently). Removed plastic shields and found the ground clamp corrosion damaged and redid the ground with a new clamp. Each device requiring grounding is individually run to and combined at this ground clamp. Although this ground clamp had damaging corrosion, most steel items had little or no rust and the steel nut unscrewed from the ground clamp bolt easily with no inhibiting corrosion. A Chrysler DIU website modulated by their repair technicians indicated that this ground was made within the engine compartment possibly for a different year. I probably should check the ground clamp on the other side.
