If your 2010 Crown Victoria has functioning headlights, brake lights, and turn signals but no tail lights, the issue could be with the tail light circuit or with a specific component in the tail light assembly.
Here are a few things you can try to troubleshoot the issue:
Check the tail light fuses. Make sure that the tail light fuses are not blown. Check the vehicle's owner manual for the location of the fuses.
Check the tail light bulbs. Make sure that the tail light bulbs are working properly, if not replace them.
Check the wiring. Make sure that the wiring for the tail lights is connected properly and that there are no frayed wires or broken connections.
Check the brake light switch. The brake light switch is responsible for turning on the brake lights when the brake pedal is depressed. Make sure the brake light switch is working properly.
Check the turn signal switch. Make sure the turn signal switch is working properly, and properly wired to the tail lights.
If the problem persist after trying the above solutions, It would be best to consult a professional mechanic or an auto electrical technician to diagnose the issue, as it could be a malfunction in one of the electronic module that control the lighting. It's a good idea to take the vehicle to a dealership or repair shop that specializes in Ford vehicles. They will have access to the wiring diagrams and repair information needed to correctly diagnose and repair the issue with the tail lights.
The ground wiring on newer vehicles is a little complicated. Older cars, the ground would have been to the body around the tail-lights, but these have a ground wire in the harness and is connected to the turn-signal switch, and other sources. I don't think you have a ground problem. Does the fuse blow as soon as you press it into the fuse-block, or when you step on the brake? I believe you have a dead short somewhere, possibly a pinched turn-signal wire close to the tail-light assembly. Brake lights work through the turn-signal wires from the turn-signal switch on the steering column. That's how you can have one side blinking for turn while the other side stays on for brake. I'm kind of shooting in the dark here because I don't know what all you've done. If you replaced the turn-signal switch in the steering column, you may have pinched a wire or something there. Another thing, if the fuse doesn't blow as soon as you press it in, will both turn-signals work as long as you don't press on the brake? If you can provide a little more information, I might be able to help you more. One last thing....Have you replaced tail-light/turn-signal bulbs? If so, be sure you used the right bulb. You should only have two bulbs, one for back-up lights and one 1157-type combination for tail-lights and turn-signals. I have seen people use a single contact (1056) bulb in place of a 1157, which creates a short from brake/turn-signal back into the tail-light circuit. I do have a 1994 Dodge Dakota.
do the signals lights work at the back if so then it sounds like you have a bad brake light switch or its out of adjustment. the brake lights and the signal lights work the same bulbs but are controlled by different circuits. the switch is located under the dash at the base of the steering colume were the brake pedal pushes against the switch.
check for power at the wires going intop the tail lights, real common that the circuit board is bad, but unlikely both at the same time. The tag, tail lights and brakes are 2 different systems. Do the turn signals work normally? if so the wiring from the turn signal switch to the brake lights is GOOD. the stop light switch had\s a ORANGE wire that should have 12V if not ck STOP LPS fuse, when brake pedal is depressed, the WHITE wire is 12V (at the stop light switch) if that is OK, the turn signal switch COULD be bad. The wiring harness plug is near the back left under the tailgate, see if that is disconnected?
you don`t say if its both or just one brake light out.you say the light itself is on but not if you mean tail light or what.the tail lights use a different filament in the bulb than the signal light which is the same filament that the brake light uses.if the signal light work on the rear then the bulbs are good,if just one side works then the bulb is no good on the side that doesn`t work.if the signal lights work but neither brake light works then you need to check the fuses in the fuse panel under the dash on the drivers side.if the fuses are good then it will be either a bad wire at the brake switch or a bad brake light switch,this is located on the brake pedal lever under the dash.
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!
If both tail lights are not working it is likely to be a fuse or bad connection under the hood or a connector at the back see if you can trace the wires to a connector and see if it is dirlty or corroded.
CHECK ALL LIGHT BULBS IN THE BACK. PROBABLY HAVE A FEW BAD BULBS THAT ARE BURNT OUT COMPLETELY. CHECK LICENSE PLATE LIGHTS ALSO. CHECK FUSES TOO TO MAKE SURE THE TAIL LIGHT FUSE IS GOOD.
sounds like a broken wire in the harness. look around the bumper area,sometimes along the frame. may have to peel back some tape covering. also if you have a trailer harness look closely at those.
