Detailed Description

This Dorman wiper motor and linkage assembly is engineered to match the function and performance of the original equipment design for the listed vehicles. It is a specific-fit replacement for 2003-2007 Ford Explorer, 2007 Ford Explorer Sport Trac, 2003-2007 Mercury Mountaineer, and 2003-2005 Lincoln Aviator applications, with 2002 Ford Explorer and 2002 Mercury Mountaineer coverage for 12-pin motor configurations. This part cross-references OE-style numbers such as 2C3Z17508AA and 2L1Z17508AA for the same application. The Dorman 602-040AS is intended for buyers seeking a complete wiper transmission and motor assembly rather than replacing individual linkage components.

Common Problems This Assembly Can Address

• Intermittent or inoperative windshield wiper movement
• Wiper linkage binding, slipping, or loss of sweep
• Motor failure causing slow, erratic, or no operation
• Excessive play in the wiper transmission mechanism
• Restoring proper windshield clearing on Ford Explorer and Mercury Mountaineer models

Installation Notes and Tips

Verify the vehicle year, make, model, and motor connector style before ordering, especially on 2002 Ford Explorer and 2002 Mercury Mountaineer applications that use a 12-pin motor. This assembly mounts with a bracket and bolt attachment, and mounting hardware is not included. Confirm the wiper arm pivot point diameter and the existing rotation direction match the replacement part before installation. For best results, inspect the cowl area, linkage pivots, and wiper arms for wear before installing the new assembly.

Quality Assurance

Dorman supplies this assembly as a standard replacement part designed to restore original-equipment-style wiper function for the listed vehicles. The steel frame, electrical drive, and specific-fit construction support consistent operation in the intended applications.
