With new bulbs, new sockets, and checked all the fuses the left brake light doesn’t work. Running lights, hazards, and turn signal all work from that bulb but the brake light I can only get to work for a few minutes after an hour or half hour of playing around with it. Then when I go to drive and get back I check it and it’s off. Not too sure what to do other than tear my car apart looking for a partially broken wire at this point. If anyone can help me out and tell me where to look or replace or anything I’d really appreciate it.

Can you clarify what you have to do in order to get it working for a little while? That is odd that it works and then stops. What do you have to do to get it working?

I would not pull the car apart. I agree that it sounds like a wire. I would just run a new wire and cut the current one at both ends and solder in the new one.

However, let us know what you have to do to get it working and we can go form there. Thanks

All I really do to get it on is tinker with the fuses, Or pull out and insert the bulb in, or pull off the pigtail connector to the sockets. Any of is usually what gets it to turn on. The main reason I am confused is that it works as a running light when I turn on my lights manually but not as a brake light after I drive the car for a little bit.
