All of the brake lights on the tailight are out except the 3rd brake light in the back dash. I checked the fuses, checked all the bulbs checked the sockets. I been told that it sounds like the switch and that the portion of the switch that controls those lights may be bad, and i've been told that its not the switch as the third light would not work either. I've also been told its a wiring issues. All these statements are from different Honda Dealerships, and honda acura certified shops. Im so confused and im not trying to waste a ton of money just to diagnose it
Hi!,
To me it sounds like a grounding issue...it's an 8 year old car so quite
possibly the chassis ground that the tail lights connect to is no longer
good. Probably a black wire going to a bolt screwed directly into the
body of the car. Have to unscrew it sandpaper/wire brush clean the
connection
coat with vaseline (prevents re-rusting) and retighten. Good luck!

Is this the main ground to chassis in the front of the car, or the rear??
