Question Headlights flicker when turn signal is applied

As the the title of the thread says, my headlights flicker when I engage the turn signals. I've found that there is a little bit of play in the switch used to turn on the headlights so when I use my turn signals, the headlight switch jiggles and the lights flicker. When the lights flicker I notice a clicking from the glove box area too.

This is on a 2002 WRX where the headlight switch is a knob at the end of the turn signal arm that you twist and there is just a bit of play when the lights are on. I can also get the lights to flicker if I turn on the lights and then rotate the switch that little extra movement that the switch has.

Sorry for the long story...I hope this is kind of clear.

Anyone have this experience or know how to fix it? Would I just need to replace the turn signal arm or does this sound like an electrical problem?

Thanks for any help.

It's possible that it's an electrical problem, although it's unlikely. You should be able to simply replace the turn signal/headlight multi-function switch and be good to go.

Your best bet would be to take it to a dealer and have them diagnose it for you. Just because you bring your car there doesn't mean that they have to do the repair work. It's actually not that difficult a job to do yourself.

I agree with silver2004impreza I used to work at a dealership and the multi-function switches would always go out just from age and use. good luck

I haven't figured it out yet but then again I haven't had time. I'm guessing I'll need a new turn signal "wand" with a new light switch.

It's the "combination switch".

My '02 Wagon was doing the same thing. It got to the point where they flickered when I indicated a turn, and everytime I would tap the brakes. Eventually, after trying everything else, I replaced the connections on the battery. I replaced them with brass connections for marine use, and the problem was solved. Looking at the stock connections, they were pretty corroded and there's only a small bit that actually touches the battery anyway. Try that and see if it helps.
