What Causes the High Beam to Not Work While the Low Beam Functions Normally?

[DiElias]

When the high beam does not work but the low beam functions normally, it may be due to a malfunction in the high beam fuse or relay. Here are the solutions: 1. Replace the fuse: When removing the old fuse, do not use your hands; instead, use the small clip inside the fuse box to pull out the fuse. When installing a new fuse, ensure it has the same specifications and model as the faulty one. 2. Repair the coil: Relay failures are often caused by damaged coil insulation, mechanical damage leading to inter-turn short circuits or grounding, or poor contact with the static iron core. During repair, the coil should be rewound. If the armature does not engage after the coil is energized, it may be due to a disconnection at the coil lead connection. After identifying the disconnection, simply solder it back in place.
