From the shop

This module quietly runs a handful of unrelated jobs — wipers, window and lock switches, the chimes, keyless entry, interior lighting — from one board. That's why a failing unit doesn't pick one thing to break. When it starts going, you'll notice several of those functions acting up at once instead of a single circuit dropping out. Tested functional. Cleaned. Mounts front, left, upper. This unit requires programming to your vehicle after installation. Fits 1997–1998 Ford Expedition; 1998 Lincoln Navigator. Part numbers: F75B-14B205-AC, interchange F75B-14B205-AB. Check your old module's tag against those numbers before ordering. Ships same day Mon–Fri if you order before 3pm EST. — Hubes

The water actually drips down onto your gem module.
