Wife bought 98 F150 XLT over the weekend and after getting it home I noticed there were no dome/courtesy/cargo lights. I checked all the fuses (No Owners manual either-of course!) No problems. Logged on to this website and found dozens of postings for lights that wouldn't go off, but none on my problem.Sprayed door with carb/choke cleaner, lubed latch anyhow.Inspiration struck and I removed dome light cover-NO BULB! Same thing for courtesy and cargo lamps! Previous owner must have had stuck switch and removed all the bulbs to "correct" the problem. Thanks for pointing me in the right direction.

 

and welcome aboard

 

Sounds like a lazymans way to fix the problem removing the bulbs how lame can you get.
