I read about your problem before I went out this evening and had a quick look at jamb switch while sitting in the '98. (What else are husbands supposed to do while the wife gets ready.
)
It looks to me that they are designed to be removed from the front rather than rear of door jamb. I would suggest you try and fish the wire out from outside first to avoid having to remove moulding. A stiff
insulated wire (say a 14 guage house wire) should do the trick. Make a small hook on end and go fishing. Needle nose pliers would be handy to grab the end if you can bring it into sight.
Fortunately the doors on these cars open extra wide so if you shine light in driver's footwell you might be able to peek in the hole and see where to aim.
If this doesn't work remove moulding to gain access. (Edit: another post was added as I was typing indicating access is PITA - go fish first)
Good luck and keep us posted.
