The ground of the tail light assemblies is faulty.
If the lights are on AND this causes the brake lights to work differently,
then the ground is the definitely the problem. If the turn signals and the
brake lights are the same light bulb, then the turn signals should work
differently when the lights are on and the ground is defective. (I am not
sure, but I think the turn signals on that car are actually a different
bulb, so they not behave as I described.)
The light assemblies are grounded through either a wire or the mounting
screw, and the ground is defective causing the lights to not come on. Take
the screws out, remove the lamp assembly, locate the trace on the assembly
that goes to one of the screw holes, and clean it and the portion of the
body where it makes contact. If the trace is broken of corroded, then you
may be able to fix it by splicing in a wire.
You need to be certain that you are installing the correct light bulbs too.
The running lights/brake lights are actually the same light bulb with two
filiments inside. If you are installing a bulb with a single filiment, then
there is no point in checking the ground because you haven't even got the
correct light bulbs.

4. Tail lights and rear side tail lights do not work when lights are
1. Replaced tail lights completely
