What Causes One Side of the Daytime Running Lights to Not Work?

[Hallie]

It could be due to a blown fuse, a short circuit in the bulb, or the bulb being burnt out. Typically, if one headlight is not working, it is often caused by the bulb burning out. Here is some relevant information: Solution: The vehicle's circuit fuse box is usually fixed under the hood in the engine compartment, near the fender. You can locate the fuse positions for the left and right headlights by following the diagram, use the provided clip to pull them out, and check if the contact points at both ends are melted. If there is a gap, it indicates the fuse is damaged. Daily light inspection: Check if the front daytime running lights, low beams, high beams, horn lights, front fog lights, turn signals, and hazard lights are functioning properly.
