I bought a 2009 Acura TL three years ago and it was in perfect condition with only 22000 miles on it. The only issue it had was that it was in for maintenance for an unknown blinker issue. Fast forward to present day, whatever they did to fix it has returned. The left turn signal sometimes will work and sometimes will not. If I turn the steering wheel all the way to the right, you will hear the normal audible clicking. Sometimes when it is not working, you will see the lights blinking as normal but you will hear no audible clicking or you will hear the rapid audible clicking. I have since switched out the turn signal module, but it did not fix it. Any help is greatly appreciated because I am clueless at this point. Thanks

 

Have you changed the bulb?

 

I honestly have not because all of the bulbs are working. None of them are burned out. FYI, the tight turn signal works perfectly. And for some reason, like previously mentioned, the left turn signal will at random begin working again.

 

The turn signal bulb is dual filament so one could be out but not the other.

If you're having an issues with the turn signal, the first thing I would look to replace is the bulb itself before tackling the turn signal relay and potentially the clock spring or turn signal stalk..

 

All right that's what I will do when I will check back. Thanks.
