My third brake light on my 09 Aveo has stopped working. I ordered a new brake light and confirmed it works by connecting it to a Duracell Battery. The connector to the third brake light is not reading any voltage, the other 2 brake lights work fine. Fuse has been checked and its good. Brake light switch has been checked and its also good. What am I left with? A faulty connector the third brake light? Is this a common problem? Whats the remedy?
