passenger head light low beam inop High beam works

[BLACKMARAUDER04]

My Passenger headlight, low beam will not work. High Beam does work.
I replaced the bulb, tried a new headlight, and replaced the LCM (with my extra).
None worked. Any suggestions?

Bad headlamp socket, bad wiring, did you check for voltage at the socket with a dvom?

No, I wouldn't know what to do. Why would High beam work, and not low beam?

Trying to figure something like this out over the internet without any type of diagnostics will be impossible. I'll guess your new bulb is bad? Maybe a rodent chewed a wire in half, maybe the connector is bad on the low beam circuit. There are a lot of possibilities, without knowing if voltage is present and how much voltage, it makes it very difficult to determine the actual cause.

because the high and low beam do not share power, only ground, hence why the 9004/9007 socket has 3 wires. One for high beam, one for low beam, one for ground. When you flip from low to high it powers a different filament inside the bulb.

You're going to probably have to probe wires with a voltmeter and start tracing things back. To rule out the harness that goes from the headlight bulb to the car, you can swap that from side to side and see if the problem follows.

I could be wrong on this but I swear each low beam has its own fuse, I remember dealing with this when I did my projector retrofit and popped a fuse. Check the owners manual on that one.

Correct. Passenger compartment fuse panel.
#24 10amp left hand (driver side) low beam
#26 10amp right hand (passenger side) low beam

[BLACKMARAUDER04]

The correct answer was: check the fuse.
#26 10amp right hand (passenger side) low beam was fried out.
replaced. Works great.

Could have swapped lights left to right to make sure it was not a headlight harness issue. Been there.

The manual does help to find fuses, glad you found the issue without tools..

Now to find the power to ground issue that blew the fuse
