Hi Ken, and Welcome.

Your problem is very common. Check out the attached link for a couple of dozen people that had the same thing happen to them.

Enjoy the site, and stop down in General Discussion for a proper welcome.

 

Check out that link.

Like he said in that 2nd post in the link spray a buncha WD-40 on the door latch.

Worked for me

 

That helped me out. Thanks. I just bout a used f-150 about a month ago and the dome light was pulled out. I couldn't figure out why. So I bought one and put it in, and all the time the ajar light would come on, so I took it out. But this is nice, now I can fix it and have a dome light. YAY!!!
