    It sounds like a door switch problem to me. Have you checked that yet?

    I see you edited your post and added a line. I would think there has to be some sort of switch to turn the light off when the door shuts. Even if it's breaking a beam of some sort. Sorry, but I guess I can't help you.

    Hey Bud. I have a 1997 f-150 with the same problem, I was told to spray wd-40 in the door latch until it runs out the bottem of the door it worked great. There is a magnetic contact in the latch that gets dirty. Good luck.

    I just like to say a BIG thanks to HARVESTMAN for
    tiping me off on the use of WD40 to fixing my
    DOOR AJAR LITE staying on problem, Just a little
    spary and the problem go's away. Never would have
    guessed that WD40 would fix that problem. THANKS.

    I put up with this problem for the last 5 years on my 97 F150 Extended cab. Will have to try the WD40. Usually shuts off dome light after starting to drive however is very annoying if it sticks and you are tring to plow at night.
    Thanks for the info!!!

    Ford has many many f150's doing this. Mine included. That is all the dealer does to fix it. A couple of shots from the wd-40 and fixed. My 98 works like new again.
