The owners manual does mention "These relays are located on the reverse side of the passenger compartment fuse panel. To access the relays you must remove the passenger compartment fuse panel.
I have never removed the fuse panel on an '02, can't advise about doing it. However I see no relay there which is listed as interior lights. Possibly the battery saver relay would do that? You could try it and see.
It seems like pulling fuse #17 might do the same thing, but you have already done that.
I'm no fan of their diagrams but the one I posted makes it look like you could unplug the offending door latch switch instead. If you can find a wiring diagram that shows the wire color for it (if it is not the same as on the diagram I posted) then you could use a multimeter with insulation piercing probe tip to measure which one is shorting to ground when it shouldn't be (when latch is in closed position), accessing the wire where it leaves the door so you aren't tearing door skins off of them all.
If you don't have a multimeter then I would advise getting one. If you have one, but no insulation piercing probe tips, a crude version of probe tips could be made by taking a needle and piece of thin wire and using the wire to lash the needle onto the multimeter stock probe tip. I wouldn't want to use that long term but to check 4 doors and the back hatch it could help.
Once you pierce the wire you would measure for resistance (or continuity mode) to chassis ground, with the one grounding in a latched latch position being wrong, unless the diagram was illustrated the reverse of what it should be, then all the rest would normally grounded and the one offending switch would be open circuit instead of grounded.
There may be some other tips in the linked video. He talks about a test using a paperclip around the 12:15 mark.
