Verify vehicle fitment by year, make, and model before installation. This assembly uses bolt-on mounting and is specific to the listed applications, so confirm the wiper arm pivot point diameter and mounting layout match the original unit. The package contents include 1 wiper transmission assembly. For best results, inspect the wiper arms, pivots, and electrical connector condition during replacement.

Quality Assurance

Dorman supplies this assembly as a standard replacement part intended to restore original equipment-style operation on the listed Ford and Mercury vehicles. The 602-321AS is built as a new replacement assembly rather than a repair-only component, helping address the motor and linkage together in one service part.
