All of the lights work except for one low beam headlight. The running lights work just fine but when you flip on the lights only the passenger side headlight works. Although, the high beams work just fine for both headlights which are from the same light bulb. I tried replacing the light bulb first but it did nothing. The drivers side low beam headlight still will not turn on.

 

check the positive side of the socket to make sure its got power going to the socket with the switch turned on. sometimes the sockets go bad

 

Do you know where the ground would be though for the low beam driver side? I am having difficulty hunting it down. There is no power at the plug or before it. (I stabbed a little hole in the wire just to check to make sure it was not the plug) I also replaced the switch on the dash for the lights hoping that would fix it. Although, there is still no power.
