Repair Procedure
WARNING: This page is about a different car, the 2002 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Insert pre-stripped wire ends into proper size waterproof butt-splice connector, and crimp connector using appropriate crimping pliers. See Fig 1 . Using heat gun, hair dryer or match, heat splice until it shrinks and adhesive oozes from each end of tubing. Connection is now waterproofed.
