Low beam out on one side

[burlsube]

I'm sure this is basic, but I'm still coming up to speed on all things rover.

My left side low beam isnt working, high beam works fine. The fuse is fine as is the actual light. The light is a led Trucklite. I swapped it with a known working light just to check. What else am I missing? Is it the harness, connector, switch? Before I start pulling things apart I wanted to consult the hive mind.

Obviously recheck the low beam that side fuse . Then use a meter to check bothbsides of that fuse connection for voltage. Then check the headlamp ground to the inner wing. Also swap the headlamps to make sure you don't have a.dud

Does the low and high have a separate fuse? I assume not. I upgraded to the ato fuses so my fuse mapping is a little funky.

 

[Red90]

Yes. There is a separate fuse for each. In other words there are four fuses. Get a manual and look at the wiring schematic.

I had the same issue when I upgraded my headlights to LEDs a few weeks ago. I pulled the fuse and reinstalled it which fixed the issue. Not satisfied, I pulled and cleaned each fuse and fuse socket in turn. No issues since.

I had this happen on mine and it ended up being the ground. I would double check it, I accidentally loosened mine when I was moving wires around and cleaning things up.

A bad ground would kill the high beam as well.

So no power in the headlight socket. BTDT, for me it was a matter of replacing the H4 socket plug itself. The connection had corroded away over time.

 

[burlsube]

Thanks. It looks like the issue was the terminals in the fuse box had some corrosion. A little cleaning and I was back in action. Now I need to figure out where the water is coming from.
