    Hi all!

    Ive done lots of research but this problem still has me stumped.
    2005 Explorer

    Symptoms:
    -neither of the rear running lights work (the fronts do work)
    -passenger side rear directional and brake light do not work. The front passenger side direction does.
    -automatic headlights work, but the dash lights do not work when automatic lights are used. The dash lights do work when the headlights are turned on manually.
    -the license plate lights do not work
    -third brake light does work
    -both the driver's side brake light and directional work
    -reverse lights work
    -at one point the driver's side directional and brake light were not working, for a day

    What I've done:
    -replaced the rear bulbs
    -cleaned the connections of the rear bulbs and swapped the sockets
    -cleaned and inspected the connection at the multifunction switch in the column, everything looked fine.
    -cleaned and inspected the connection at the headlamp switch.
    -inspected a bunch of fuses, I forget which ones.

    This has got me stumped!
    I suspected it may be a ground problem but Ive read the two lights share a common ground.
    I have also read there may be a dirty connection at some trailer light junction. it looks like a b**** to get to.

    Any Ideas?

    Im not sure if this happened all at once or over a period. Right as I saw the right rear directional wasnt working I noticed all the other lighting symptoms. So probably all at once but there could have been malfunctions before too.

    The only malfunction which I noticed existed before the right turn signal was the dash lights not comming on with the automatic lights. Thats been happening a while

    i would start with the battery grounds, there should be one to the body of the car and one to the engine.if they are dirty or lose clean them..
