Hey there, so here's the picture:

1992 XJ Laredo 4 door, 4.0l, AW4, No real upgrades except a mild lift

Now that you know that stuff (which has nothing to do with my issue) here is my issue. I was re-wrapping the headliner and upper trim in my XJ yesterday, and I noticed something as I was cleaning up. With the door open, all four dome lights turned on and off as normal, except the passenger rear, which stays on. With the door closed, however, none of the lights turn on. Could this be a fuse issue, as in there is a seperate circuit going to the overheads with the door open vs. shut?

Thanks!
