How do I remove the rear wiper assembly on a 2000 Mercury Villager?

First Raise the rear wiper blade assembly out away from the back glass it will pull away from the body of the van.

next there is a plastic clip located on the wiper shaft pop this clip off.

After you have removed the clip slid the wiper assembly out of the slot.

This should allow complete removal.

Next step re-install the new wiper in reverse.
