Drivers side brake light doesent work,changed bulb,still won't work

take it to a body shop

try checking the relay and loose damaged wireing to to lights

replace the bulb

sounds like you have a short in the drivers side brake light. it may be due to corrosion in the bulb inlet.try cleaning the bulb socket itself with wd40 or add bulb grease to the bulb. you may have a broken wire to it also.check with a test light to confirm you have power to the bulb when brakes applied,this will take 2 people 1 to press brakes and1 to check for current with a test light at the tail light itself. you may only have corrosion in the brake light bulb socket,so,,do this 1st. with lights off,, remove the bulb on driversside, add a little bulb grease to your bulb,insert it into the bulb socket,and then remove the bulb again,do this 3 times,make sure the bulbs getting connection. then apply the brakes and see if the light comes on. thank you for choosing fixya.com

That has a double filament bulb in it. One is for the tail light and the other for the brake and maybe the turn signal. If your turn signal flashes the tail light and not an individual turn signal bulb it will behave the same way. The way it works is that the tail light filament goes off and the brighter brake light filament comes on. The brake light half of the bulb is out. If you change it, change the passenger side too, it will do the same shortly if you leave it in. They tend to go bad in pairs. Good luck.

Sounds like you need to replace the drivers brake/tail light.

CHANGE BULB ON LEFT SIDE WITH PROPER BULB

Use a 12 Volt test light at the tail light connector and see if power is present at the harness, this would indicate a possible defective bulb socket.

Ok you can't tell anyone, but I changed the wrong bulb. Only two choices and I changed the good bulb. ugh. all fixed now..

The bulb actually has two seperate elements in it.
That is why the tail light works fine.

If you take the bulb out you will see the seperate elements.
Change the bulb and it should be fine.
