Question about 2004 Chevrolet Impala
My front lights and back lights work but my rear turn signals and brake lights do not work. I checked the fuses and they are great!
These bulbs have two seperate eliments to burn at different brightness. it is possible that one eliment is burned out. it is also possible that the bulbs are not seated properly in there sockets.

The problem is the turn signal/headlight/hazard switch assembly on the steering column which the brake light wiring runs through. The part is easy to change and cost about $50 at most parts stores

check the wiring from the tailights back to the fuse panel, it sounds like an open connection. if i recall correctly check under the dash on the drivers side near the fuse panel for a bunch of wires in a bundle and look carefully for a wire or two that are cut/shorted/or seperated, you can also check under the drivers side kick panel by the hood release.

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

Try to get a schematic on your year and model truck, sometimes you can get one online or get a copy
at the library, or purchase from alldata info on just your truck, its very affordable and will give you a
wealth of info. it sounds like you have a poor ground, if you have a poor or dirty ground that is not
making good contact you will have a lot of resistance to the flow of voltage and current. in direct volts
and current voltage and current flows from negative to positive, negative=ground and positive=hot dc
if you have a poor ground you will have lights that may not work or may even go on and off as you hit
bumps on the road. you can use a test light to check for voltage, check at the fuse in coming from the
battery , the other side of the fuse, make sure you have the correct fuse for its purpose. check for volts
at the lights. you can also use a digital ohm meter. a test light is quicker, easier and cheaper for its
purpose, unless your looking for a precise voltage you want to use a meter. you can find a ground
most anywhere on your truck where you can clip your test light and probe for voltage. just make sure
the power to your lights is on. good luck!
