Dorman 742-578 Window Lift Motor
Features:
- Seamless installation – features proprietary software that helps ensure fast and simple calibration, with no special tools or skills required
- Trustworthy quality – backed by a team of product experts in the United States and more than a century of automotive experience
When an original equipment power window regulator smart motor malfunctions on certain vehicles, it’s often due to an electronic failure. Replacing it with the same motor design may invite similar future issues and repairs. This Dorman OE FIX smart motor features upgraded electronics for greater processing power, faster response times and better protection against voltage spikes, heat-related failures and motor stall conditions. To help extend service life, its printed circuit board (PCB) is coated with a special resin that resists moisture, dust and other contaminants. Proprietary software ensures a seamless installation and simple calibration, with no special tools or skills required. When a factory smart motor has failed due to damage, normal wear and tear or collision impact, this upgraded replacement is designed to help restore all original equipment functionality, and has been tested to meet federal motor vehicle anti-pinch standards.
