I changed my driverside brake light .. the park light works..the brake light doesnt work
is it a 2 filament light bulb? if so, you may have just got a bad bulb, try swapping it with the other side and see if its still doing it - only reason i recommend doing this is because i just experienced this with one of my cars the other day... if that doesn't work you will have to trace the electrical or check your fuses... the bulb swap is the easier of the 3 to try first.
There have been a couple of people with a bad circuit board in the rear lights. It's about a $20 part if swapping bulbs doesn't work. See if you have power in and out of the board with a meter before buying parts.
