From the shop
This module quietly runs the small stuff — wipers, washers, interior lights, power windows and locks, chimes, keyless entry. It doesn't drive the vehicle, but you notice fast when it stops managing them. Fits 1997–1998 Ford F-150 and F-250. Owners usually describe several of these acting up at once rather than a single item going out, which is the pattern worth checking before you assume separate problems. Part numbers: F85B-14B205-NA, interchange 591-00294D, F85Z-14B205-NA, EL3Z-14B205-CRM. Tested functional. Cleaned. Mounts front, center. This unit requires programming to your vehicle after installation. Compare your old module's tag against these numbers before ordering to be sure. Ships same day Mon–Fri if you order before 3pm EST. — Hubes

Please note: Drivetrain / Trim Spec: 4x4 (4WD) models equipped with Electronic Shift-On-The-Fly (ESOF), Power Windows (PW), and Power Locks (PL). Programming: this GEM stores the truck's as-built option configuration, and that configuration is encoded in the part number — which is why the family splits by drivetrain and power group. Replacing the SAME part number with the same options is a straight swap; a different GEM part number or option set needs dealer as-built programming. Matching the part number on your original unit’s label is the zero-risk path — message us your VIN or label number and we’ll verify.
