How do you change the light bulb in the third brake light of a 1989 Chevrolet Caprice?
i have a 93 caprice so this may not apply, but the bulb goes into a socket underneath the assembly. you can get to it thru the trunk. you don't even need any tools to do it. open the trunk and check around underneath the brake light. Unscrew the brakelight mount and turn it so it is easy to unscrew the bulb first. Then unscrew the bulb, it may take a few tries to get it out. If you still have problems unscrew the top of the mount (they're the only screws left on the mount) then try to remove the bulb.
