My driver's side headlight is out, i tried replacing the bulb and it still won't go on. The high beams work though. Does anyone know what it could be?

 

There should be 3 wires going into the light clip. One is ground, one pos for low beams, one pos for high beams. I would start by taking the voltmeter to the wires and make sure you are getting power to the bulb. If you are, make sure it is enough power (over 11v or so). If no power at all there is probably a fraid or burnt out wire somewhere, if it is a matter of low voltage, wire in a relay. If it were me and there was no power going to it, I would wire in a new switch, it may look ghetto, but I am too lazy to trace wires around looking for a bad wire.

 

check it back to the relay.

 

Could be a faulty wire or the harness or the connector. I had the same problem a couple of nights ago, mine turned out to be a bad connector.
Start troubleshooting at the bulb end of the connector and work your way back

 

Ok thanks i'll try all that.

 

same thing happened to me but i found out it was the new bulb that i put in. low beam was also busted on the new one.
