From the shop

This module quietly runs a handful of accessories most people never think about until they quit at once — wipers and washers, power windows, door locks, interior lighting, the warning chimes, keyless entry. That's the tell with these: rather than one function fading out, several of them start acting up together, and that's when folks call. This unit requires programming to your vehicle after installation. Tested functional. Cleaned. Mounts front, left, lower, driver side. Fits 1997–1998 Ford F-150 and F-250. Part numbers: F65B-14B205-BB, interchange F65Z-14B205-BB. Ships same day Mon–Fri before 3pm EST. Check your old module's tag against the numbers above before ordering, just to be sure. — Hubes

The water actually drips down onto your gem module. So use the Fitment tool on my website, drop your make model, gear in the comments, and I'll help you diagnose the issue and we'll get you set up with a replacement gem.
