Hello.

I recently noticed that my when i press on the brakes the passenger and third brake light are fuctional but the driver side brake light will not illuminate.Sometime it works and some times it doesn't. I changed the bulb(the one with two filaments) figuring just the brake light blew.The rear parking lights work fine.Also there is a ground wire (blk. wire) that is NOT connected to any part of the chassis back there. I thought that there is one ground wire per light assembly but there is two ground wires on the driver side.One is connected and the other one isn't. Maybe this why my drv.side brake light will work sometimes. WHat do you think? Thanks for the responses.

Clean up the three ears on that socket real well. Use a fine file or sandpaper to get corrosion off. Make sure there's no corrosion inside the socket, if you find any, scrape it clean.
There should not be any corrosion on the taillight socket. I know it's tough to get into the hole it lives in, but if you can't see it or you see corrosion and can't get in to clean it off, you may have to pull the taillight completely and clean everything up.
Also, if the bulb is coming out white or cracked - you have water in the taillight. Usually this is a sedan problem but wagons get it too. Try drilling a very small (3/32) hole into the lens at the bottom outside corner.
Dry out inside light with air, hair dryer, or paper towels.
Make sure all fuses are ok too, though I don't think this is the problem today.

Try grounding that wire and see what happens.Is this a sedan or wagon?
