Wiper Motor
Mack

This motor powers the windshield wiper action and is engineered to deliver reliable operation across a wide temperature range and in challenging weather. The wiper motor drives the linkage that moves blades across the glass, providing consistent sweep patterns, park position reliability, and adequate torque even when parked in heavy snow. A robust motor includes sealed electrical connections to resist moisture intrusion, bushings or bearings designed for long life, and protection against vibration to prevent arcing or misalignment. When the motor sluggishly returns to park, stalls, or produces intermittent motion, replacement is warranted to restore visibility and weather safety. Installation should align with the wiper arm assembly, ensure proper electrical connector compatibility, and verify that the park switch synchronizes with the wiper linkage. Regular checks help detect gear wear, corrosion, or stuck linkage that could hinder performance. For dependable sourcing, Source One Parts Center has wiper motors designed for rugged duty.
