SOURCE: Problems with brake lights on my 2000 Jeep Grand Cherokee

YES -- process of elimination. Obviously there's a short circuit in the Brake/Headlight circuits - right? Blown fuse(s) is/are evident of this -- would you agree? Which fuse(s) is/are blowing? An analysis tells you that the only time a fuse blows is when the headlamps are turned on -- correct? Otherwise, brake lights work normally -- right? OK. Head lamps have relays which turn them on. Here's a wiring diagram of the 2000 Hyundai Sonata (NOT the Jeep Grand Cherokee)
7a9e354.jpg a663f53.gif It would appear the problem is with one or more bulbs or sockets or both. As you many notice, there are no connections between the headlamps and brake lamps except the parking lamps (which share the bulbs/sockets)
c7068ec.gif When the headlamps are turned on, so does the tail lamp relay. As you can see, these bulbs/sockets are 'DUAL' filament to ground (series-parallel circuit). Just a guess here - the short is in one of the lower rear brake/parking lamp bulbs/sockets.... just a guess.

SOURCE: no tail rnning lights-brake and backup works-wire

It may not be a fuse at all it sounds from the description (14a) it is a 14 gauge fusible link which is a wire that will burn out like a fuse, check for 12 volts with a multimeter or test light from the fuse box and then continue down the circuit until you cannot find power. Just before this point you should be able to see a part of the wire that looks different and that should be the fusible link.

SOURCE: brake lights don't work

This sounds like a bad brake light switch, this switch is located on the bracket that holds brake pedal,you can test for power at switch,also if you remove connector and jump terminals with a wire and see if lights lite, if lights light then switch is bad,

On my 2010 crown vic I have headlights but no tail lights. I do have brake lights and turn signals.

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.

I have a 05 nissan navara d22 and last week the tail lights have stopped working. Its just the tail lights. brake lights ok. reverse ok and the turn signals are all ok. fuses are all ok. is there a relay i...

the tail lights and brake lights are on a different circuit so if one goes out you still have the other was your car serviced recently the mechanic might have taken it out so you can come back to spend more$$$ check the owners manual for the fuse value EX. 5amp -15 amp? and put it in the open fuse space in the power distribution box behind the battery this will probably fix your problem and unmask a rotten mechanic if you don't have the owners manual you can search it on the net and look at the power distribution box diagram it will tell you the fuse value that should be there LATER MAN!

It can be faulty brake light switch causing the problem or its blown brake light bulb. First check and confirm brake light lamp is working and that's not the case.

What is the fuse called in the fuse box for tail and brake lights havng problems finding the right one

Hi, tail and brake fuses are separate. Brake fuse is usually labeled STOP LMP, and tail is usually PARK LMPs. If you can be more specific about the problem you're having and the model and year of the car, I will see if I have the wiring diagrams to help you.
