DOOR AJAR LIGHT WILL NOT TURN OFF

1999 Ford F-150 • 5.3L V8 4WD Automatic • 140,000 miles

While driving my door ajar lamp stays on causing my interior light and outside cab light to stay on then when I'm parked and truck is off those two lights stay on until I finally unhooked neg. Battery cable. If I hook the cable up after few hours it resets the computer I guess so it works normal for about five minutes then the lamps come back on while driving. Obviously I have made sure all doors are closed tightly but it doesn't help

Have it scanned by a pro as it may be the body control module

Thank You
Would that also make it so the power locks don't work?

It cold but check the fuse and relay if it has one in the underhood box.

Once again Thank You and is. There a way to tell if a relay has gone bad?

They can be tested but easiest way is to just switch it with a like relay
