What is the reason for one side of the Accord's daytime running light not working?
1 Answers
The reasons for the daytime running light not working can be summarized as follows: first, the voltage regulator is burnt out; second, the daytime running light bulb is burnt out; third, there is a wiring issue. Below are the detailed explanations: 1. The fuse of the daytime running light is blown: If the fuse is blown, usually both sides will not light up. If only one side is not working, it is not a fuse issue. 2. Wiring harness failure: Check the wiring harness between the headlight control module and the daytime running light. 3. Fault in the light guide ring driver: For example, loose or poorly connected driver plugs. 4. Problem with the daytime running light bulb: If there is an issue with the filament quality of the bulb, its resistance will increase as the temperature rises, leading to a decrease in the working current, which will cause the daytime running light to turn off.
