I hear the clicking or buzzing when I use my turn signals. Even the hazard lights do a click sound but no turn signals light up on the dash or outside of the car. All interior iteams work great still. All other lights work great too. Just anything involving the turn signals. I read that it could have been the etacs ecu. I got another one but still fails the turn signals on being used. Any help or ideas will be greatly appreciated.

 

I'm having the same issue. I hear a noise coming from the Etacs but no outside action and to top it off my brakes don't work now. I don't get it

 

Bump

 

check the relay i had this same issue and my main relay ended up going out about a week later..

 

The main relay is in the Etacs Ecu, so what relay did you replace?
