Witch of the fuse is the one for inside dash lights .

CHECK FUSES TAIL LIGHTS MIGHT HAVE LOOSE WIRR

dash lights flickering due to loose ground under dash-check fuses on the parking lamps cheers Denny

in the rear lights you may have two bulbs one is the turn signal the other one is stop light / tail light the stop light / tail light has two filaments, one for the stop light (21 watt) & one for the tail light (5 watt) it is possible that the tail light filament is blown, try replacing the bulb to see if that fixes the problem,also check all the fuses as well.......hope this helps......cheers.

Automobile companies make the dash lights stop working to let you know that the tail lights are out. Usually it is just an indication that you have blown a tail light fuse. First make sure that you do not just have the dimmer turned down on the dash lights. But if the dash and tail lights are out, first check the fuse block to see if the fuse for the tail lights has blown. If you change the fuse and it blows right away you will have to start searching for electrical shorts.
Another tell is when you notice that the turn signals are flashing faster than normal. This means that one or more of your turn signal bulbs has burned out.

most likely its your muti-funtion switch in the steering column.but first check your turn signal flasher & your emergency flasher

Look at fuse #18, a 15 amp fuse, in the fuse block. This fuse powers both the tail lights and instrument cluster lights. Usually both of these light systems are powered by the same fuse so when your cluster isn't lit up you'll know right away that your tail lights aren't working as it's not safe to drive without tail lights. Your brake, turn, and head lamps are powered by different circuits. Hope this helps and good luck!

You should have a fuse panel under you dash inside. This is where the fuses are located for lights. Don't know the exact location, but you can pull each fuse to see if it is bad. This won't hurt anything. It just keeps you from hunting down a diagram of where the fuse is located.

Hi its rob here what make and model of car is it? it sounds like the light switch is faulty but that wouldnt stop the brake lights workin try two stop and tail light bulbs then if you have stop lights your switch is at fault

One of the tail light bulbs can be shorted internally.  Replace the tail light bulbs first.  Try this cheap fix first.

I had the same problem with my 1996 Mystique about a year ago. The brake and tail lights stopped working, except for the center brake light in the window. Turned out to be oxidation of the terminals at the connector on the turn signal. Yes, that's right, turn signal. The electrical signal to the tail lights goes thru the connector on the turn signal. To fix, I cleaned the contacts and the brake lights started working again. Hope this helps. Cheers, Henry
