Recently something weird started happening. Once in a a while when I would use my turn signal my head lights would blink and I would hear the click of a solenoid comming somewhere behind my glove box. I did a little research and found out that this is a somewhat common issue. The combination switch (the switch that operates the turn signals and hi/low beams) isnt making a good electrical connection. Some people said to clean the contacts and others said to bend the little tabs to put more pressure on the contacts. Mine was rather dirty so I cleaned it.
*Do this at your own risk! I am not responsible for anything you damage*
First thing is first. You need to get into the steering column. Start off with the phillips head screw in the middle of the plastic on the bottom of the steering column. This allows you to pull the bottom piece off, its also held on by little plastic clips.
After the bottom piece is off you can access the two screws holding the top piece on.
The switch comes out after removing two screws and the wiring harness.
Now we take apart the switch. The clear plastic piece unclips.
Take out the two screws at the top along with the little wiring harness. I found it best to use a small screw driver to pry up the black plastic strip that keeps the plug from coming out. Careful that you dont break it.
The white plastic section comes up and you revile the contacts. You can see the three round ones that are surrounded by black stuff. Originally when I opened up the switch there was lots more black grease. These pictures were taken after I removed most of the blackened grease. I did not replace the grease I removed as I didnt know what to use.
Reverse the instructions and you should be able to use your turn signals without your head lights flickering (or turning off for those with HID’s). Mine has been working perfectly for the past two weeks. Your mileage may vary but if cleaning the switch didnt fix your problem its time to order a new switch.

I really appreciate this post, i searched for a long time, long time, not to mention searching all around my car for hours trying to figure out the problem. While your fix actually wasn’t the same as mine (my dirty connection was in the lever stalk itself somewhat hard to take apart, no how-to’s online) it definitely put me in the right direction. Great car and website btw, keep it up. It’s nice to see people who mod their cars right, and keep it from looking like a hotwheels car. I myself have only done a few modifications to my 03 WRX as of yet, first one i had, an 02 got in an accident, kinda put me back a few steps. Currently I’m working on putting an intercooler water spray system in, got the factory switch from an STi and everything. Also as far as unusual mods are concerned any phrase I choose, right now it says the word “Braking”. Anyways, keep up the good work.
Thanks Alot for posting this up here I was about to order a new combi switch! Thanks to you I don’t have to. You saved me $120 and for that I say THANKS and keep up the good work!
No problem.
