Door ajar problem in Mercury

I've been having the "usual" problem with the door ajar switches on my 1996 Sable (a common problem reported widely on the internet). I got
the two front door switches supposedly diagnosed as bad and replaced for about $300. I've used the WD-40/silicone lubricant spray, with only partial success.The problem is still there with the rear doors, so I bought two switches for the rear doors with the intent on replacing them myself. However, these switches are mounted on the latch assembly that is tucked well into the depths of the door, and I can't figure out how to get the switch out. I figure there is a "release" mechanism but I can't see the latch assembly well enough to figure it out. I have removed the door panel, but visibility is minimal. Any ideas on how to get these switches out?

remove the whole latch the change that little switch. Actually I would try the WD40 again first. Spray the crap out of it, then open and close the door about 50 times :)

Thanks for the detailed info. I assume that I would need to remove the latch to get to the switch. Seems like too much chance that something will go wrong and I'll wind up braking something! ;-) Unless there is a way to get the switch out without removing the whole latch assembly, I think I'll need to keep trying the spray method!! Thanks, Ron
