Interior lights stay lit

When I close the doors of the truck the interior lights stay lit, where as they use to go out after a few minutes. Is there a relay located somewhere that could be bad ? I hear a clicking sound when I pull the fuse comming from the rear compartment where the jack is stored. Could that be the place for the relay? Thanks in advance. Rick

It's the switch in the front doors. They are mounted in the door latch. Spray the heck out of the latch with WD40 and open and close doors. Interier lights will go out. Do on both doors. Note there are no switches in the door jamb. Do a search in this forum for dome lights. This is a common problem for Explorers and Rangers.
