Based on over 44 years of making top-rated remanufactured products, we've seen where: and why:original parts fail. This unique, reverse-engineering expertise is the foundation of CARDONE Engineered (CSE) Technology. The CSE process identifies and corrects original design flaws, resulting in longer-lasting, reliable new electrical motors. Product Features:100% Load Testing ensures guaranteed performance every time.Brushes are precisely designed to ensure armature and contacts are properly matched.CARDONE Select Engineered (CSE) Technology ensures that all wiper motors meet or exceed O.E. form, fit and function.Every motor is assembled with the precise amount of lubricant to ensure quiet operation and long life.Improved over original performance - Gears are designed with a stronger, less brittle material than O.E. to prevent premature wear, striping and breakage, thus extending the performance life.Magnets deliver the right amount of torque needed to withstand extreme weather conditions and to compensate for other worn components in the window lift system.
