My drivers side headlight is stuck in highbeam mide regardless of theswitch posution. Also it doesnt initialize like rbe other one does.what causes this and how do I fix it?

 

Did you try disconnecting the battery to see if it fixes itself? Maybe the plug for the headlight came loose(but this is less likely if it still works). I have a $15 copy of techstream if it where my car I would check to see if there are any error codes.
That's all I can think of other that buying a used headlight to replace it.
