How do i remove the sensor for the rear tailgate?


1) Locate and remove sensor.
The sensor is located under the drivers tail light. Unclip it from the body and then unplug it.

2) Bypass the tail light circuit.
Connect the tail light signal wire (Green) to the tail light wire (Green w/ Red Stripe). I recommend using wire tap in squeeze connectors that way you dont have to cut any wires.

3) Bypass the brake light circuit.
Connect the brakelight signal wire (Green w/ White Stripe) to the brake light wire (Red w/ Blue stripe) and the the 3rd brake light wire (Red w/ White Stripe). Again all three of these wires are to be connected together.

4) Throw away your broken Tail Lamp Failure Sensor
Do not plug your sensor back in. Doing so will cause the annoying orange lamp failure warning light on your dash to stay on. Leave it unplugged ant the light will stay off.

5) Test your work
Turn on your lights and make sure your tail lights work properly. Have a friend step on the brake pedal, and make sure your brake lights work properly as well. Dont forget to check the Third brake light.

All my lamp indicator lights keep flashing. blickers work. when you step on break the break lights work. but when driving no tail lights


First replace the tail light bulbs. The tail light and brake lights are different filaments in the same bulb. it is very possible for the tail lights to go out while brake lights still work. And somtimes the tail lights can blow out together.
If you change the bulbs and still dont work then look for other problems.

On 2002 jeep laredo brake lights dont turn on if lights arent on


That does not make any sense. Do the tail lights work? There are supposed to be separate filaments for brake lights, tail lights, and turn signals. In particular the center brake light should not be possible to be confused with tail lights or signals. Does it come on? If not, then you probably have no brake lights at all, and that is probably because of the bad fuse or the switch on the brake pedal for the brake lights.
If there is some sort of cross over between tail light and brake lights, that is usually from a bad light socket ground; which results in current backing up from one system to another. But then each is usually only half brightness.

I don't have any tail lights brake lights, and turn signals. i dont know what fuse or relay to check or replace, because I dont have a owners manual to cross reference. Oh my vehicle is a 1997 ford...


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.

Tail lights dont work


Replace the bulbs.
The bulbs will have two seperate elements in it which is why the brake light works.

Take the bulbs out and you will see the seperate elements.

My tail lights dont work, its not a fuse, my blinkers and reverse lights work, its just my running lights and my brake lights that dont, any suggestions?


check the wire harness that runs from inside the trunk on the drivers side follow it down to the tail light and make shure the wires are not damaged or unplugged remove cover on the drivers side inspect the bulbs the holders and the wires and dont forgt to retighten all grounds that you find on your travels this should get the rear tail lights working also check the brake pedal switch up on the metal part of the brake pedal arm follow it up tp the brake pedal switch and acuate the switch by hand and check the wire voltage coming in and going out when pressing the brake pedal ok give this a shot
