My driver's side headlight is not coming on. I checked voltage, and nothing is coming thru, low or high beam. The passenger side works great. Fog lights also work, turning off automatically when high beams are on.
I checked the headlight relay, and it is hooked up correctly. So my question is, does anyone know which terminals on the relay I should check for voltage in order to isolate the problem? Since the passenger headlight works, I'm thinking is a wiring problem leading to the driver's headlight. |

Start at the fuse box and check for voltage at fuses 1-4 that control the hi low left and right. Spin the fuses to make sure they make contact. A wire diagram will be helpful. |

Spinning the fuse was all it took. Brilliant response!! Thank you. That's what makes this such an awesome forum.
