I have a 91 Camaro that has a 3rd brake light located on the hatch. The problem I am having on this car is that when I apply the brake the 3rd brake light does not light up- the rear tail lights above bumper work fine. I have replaced the bulb on it twice and doesn't work. What is the cause of this problem? Where can these wires be traced? Your response is greatly appreciated. Thank you.

 

i dunno if the maros are the same as the bird, but on my 90 bird theres a little contact plate that connects to the hatch when it is closed to supply power to the third brakelights. trying cleaning off that plate.

 

91 is different. The light is at the top of the hatch and has a stretchy cord that powers it. I have a 91 Formula and mine has never worked. There are several 91-92 camaros and birds around here and none of their third brake lights work. Is this a common problem?
