    just one side or both sides?

  • Pat Tuszynski Feb 10, 2012

    Jeremy, just the passenger side. The other side is fine.

    How would I go about checking the ground? The wiring all seems to be attached correctly.

    if it where a ground the all kinds of funky things would happen like the taillights would work but both sides would flash when the turn signals on or something simular. Since the brake and turn signal use the same ground and they work fine it is likely n not the issue.

Power for the tail lights is supplied by the brown wire. Check for power on that wire at the socket. If there is no power than you will need to traced the wire and see where it is broken or not making contact. Harness connectors would be a good start as they like to corrode.

If there is power than look carefully at the socket. The metal tabs like to burn up. If the tabs that make contact with the bulb are not shiny silvery or brass looking than the socket is likely the problem.

I'm pretty sure the taillight sockets are interchangeable. You can unplug the one from the side that works and plug it into the side that doesn't work. If the light works than you know its the socket.

let me know if you have any questions and thank you for using!

Some newer vehicles have seperate fuses for lighting on each side of car, check that out first, check the ground for the socket

SOURCE: brake fluid low warning came on in 2004 Ford

Whoa, there is a line marked on the fluid reservoir that you do not fill above. Be careful to make sure that you don't get dust/debris inside the reservoir. The owners manual and the reservoir have markings to tell you what type of fluid should be used.

All signals and other flashers work but passenger front flashers do not work

Use a test light, test for power and ground at the bulb contacts. Then test for power and ground at the wires. Probably needs a new socket, common problem.

06 Taurus tail light

If you are saying a tail light does not work, and you have changed the bulb, have you checked for voltage and ground at the socket ?
Could be a faulty socket or wiring problem.

Left rear turn bulb is burnt out

Pull the trunk carpet back behind the lamp assembly. Remove the 3 nuts from the bolts and pull the lamp assembly away from the body. Then disconnect the connector to the bulb then twist the socket cc to remove the socket then pull the bulb out of socket.

Brake lights

If all of the wiring, fuses, bulbs, and switches are good (which is what it seems since everything else works fine including the turn signals on the passenger taillight), sounds like it may just be a bad socket. I have a somewhat similar problem on a 1986 F150.
