That's what it sounds like to me. I had the same problem on mine a bunch of
years back. The switch just screws into the side of the transfer case and
should run you in the $60 range.
Did you ever consider picking up a parts truck for Christine? I've seen quite
a few Gen I 4x4 Dakotas on eBay in the Wisconsin & Michigan areas for around
$500.

A $500 clunker that doesn't run may still get you doors, front diff, trans,
Trasnfer case & a tail gate which are all items you have or need to replace. If
you're lucky, maybe even a decent frame.
