I just noticed only 3 of my 4 brake lights are working. I replaced the inside passenger side bulb, but when i tested it, the light still didn't , but all 4 are lit when my headlights are on. Has anyone had this problem and what was the cure. 05 C6 coupe
So the brake light part of the circuit is compromised.
First thing I'd suspect is the main connector, accessible through the passenger side tail light openings. Especially in areas that see a lot of humidity, the pins inside that connector corrode and cause all kinds of problems.
Thank you Rick T, i will deffinately open that light up and check the connector to see if there is any corrosion and clean all lamp holders. Being in the northeast, we do see our fair share of humidity. Hell i will even hit auto zone and get some lamp grease to keep moisture out,,thanks again.
I opened up the tail light and removed the new lamp and used some baking soda and water and also used an alcohol swab to clean out the socket then put a light coat of vasalins on the base of the lamp and put everything back together, and still only 3 brake lights work. Any other ideas Rick ? This year doesn't use the old 1157 bulbs, It calls for a 3057 which i purchased.

We aren't talking about the "bulb socket" here.
We are talking about the big wiring harness "connector" inside the rear bumper/fascia accessible through the tail light openings.

Please forgive me Rick, but i thought you were talking about cleaning the lamp socket. But now i understand much better about the connector. **** Jockey was nice enough to provide a photo of the connector and now i know what to look for here, and i guess if a camera could fit to take the shot, i should be able to get my hand in there,,,lol
I know it's unlikely, but maybe you got a replacement bulb with one bad filament...try switching the bulb with one of the taillights that you have seen working.

So, was wondering if there was a resolution to this? I'm having the same problem. One brake light is not working, but they all light up when I turn the lights on, just no brake lighting on one of them. Was going to replace the bulb tonight, but curious if there is a more serious problem.
Btw, I recently changed my tail lights from the LED ones back to stock. The LED one's worked perfectly. I know beause I took pictures before removing them to place them for sale.

I was thinking this as I read the post.
