Thank you for all the input on this problem. Before posting this issue I tested all the fuses with a tester and they all tested okay. I then tested the door switch and wall switch and they tested okay. I went back to the fuse box and pulled all the fuses and took a very close look at all of them and found one that seemed to have a hairline crack.
I replaced that fuse and now the lights work. I guess it pays to use the "eye ball" test and not to rely on test equipment.
