2008 Explorer with only passenger bright light working. No idea what happened. Just quit working today. Running lights work fine. Anyone know what it could be ???

Update : I got both bright and dim working on passenger side but still no driver side . Irp;aced the bulb and still nothing

Well, I'd start with a multimeter on your headlight plug. If the voltage matches the passenger side, I'll try and think of something else. However, if the voltage is off or null, have to start tracing lines from the plug back to where they split off left and right.

If you don't know how to use a voltmeter, it's actually very simple. Hit me back if you need help. You can pick up a cheap one at Walmart for like 8 bucks.
