I have a 2004 f-150 super cab, the low beam on the passenger side does not work, the high beam works fine on the passenger side, the low and high beam on the driver side work fine. I replaced the bulb and the low beam still did not work, the main fuse for the lights is good, I was told that there is a low beam fuse, I need to know where the fuse is located so i can replace it.

Your fuse box is located in the passanger side where the feet are on the right. There is a plastic cover you take off then another black cover you also take off.

Then look at the diagram in the manual I sent you and locate #23.
