The combination light switch connector in my car is experiencing problems with heat in the low beam wiring. It is the same problem as listed under other Civics from the model year range, but mine is not included in the recall. It may cause the low beams to go out and cause visibility issues when the wire becomes too hot.
Takata recall: there have been numerous times where I have either called or went to a Honda dealership to have the airbag inflators on both the driver and passenger side, fixed to avoid harm to myself or others. In almost three years, I have not once heard back about the dealership receiving parts to fix the issue. I have never received notice, nor was I told about the recall with the wiring harness terminal for the low beam headlights. Honda needs to fix this issue because it is a huge safety hazard that can get people killed or seriously injured.
Driver side headlight stopped working on dim only. Changed bulb, but this bulb also did not work on dim. Verified the bulb was good by trying it on the passenger side. The next day, the driver side headlight just started working again. 3 weeks later it went out again. This time I traced the wiring back inside the car to the "inside" fuse box. The wiring that goes out to that headlight comes from a plug that plugs into this fuse box. After "wiggling" this plug, the headlight came back on. However I can "wiggle" it and make it go off also. Just wondering if anyone else has had this problem.
