My friend’s car was having problems with the headlights and tail-lights/driving lights. The head lights would be on, but the tail lights would be out, or the tail lights would be on but the head lights were off. When the tail lights were out, so were the dash lights. I researched the cause of this problem a bit and it turns out that the combo switch, or combination switch, on the steering wheel could be a likely troublemaker. This switch can also cause the blinker not to work, or to work intermittently and it can also cause problems with the high beams being stuck on, high beams not working or high beams and low beams being on at the same time.
I removed the steering wheel and detached the combo switch and popped open the side that’s used to control the headlights, tail lights/parking lights/dash lights aka running lights and discovered the contacts were in extremely bad shape. I was able to sand the contacts down a bit and get them back to a very shiny surface. I started with 600-800 grit sandpaper, then went to 1000, then 1500. I finished the contacts with 4000 grit sandpaper which gave them a nice smooth surface finish. The combo switch is working great now. Check out the video I made below which shows how to repair your Honda Accord Combo Switch. This particular vehicle is a 87 4 door sedan but it should work for models between 1984 and 1989 with minor variations.
This video is also useful if your windshield wiper combo switch is giving you problems. While I don’t open up the windshield wiper combination switch in this video, the procedure is the same up until the part where you clean the switch contacts. As usual take the switch apart slowly to make sure no important parts fall out and you should be okay. The video is extremely detail in the removal of the switch and the re-assembly, including how to torque the steering wheel and disconnect a car battery.
I hope you find this video useful, if you do, please leave a comment here or on YouTube to let me know if you used it and how it worked out for you.
