96 safari dome lights

My dome lights do not shut off. I have disconnected all the door switches and checked, they work. I have to pull the fuse out but that is not too handy. What next"

Is this by chance, a conversion van, or is the interior factory original?

I am having the same problem with my '95 Astro.

Is your problem continuous or occasional?

check all the door switches, our 96 did the same thing. turned out to be a loose door switch
