One New Front Left Power Window Regulator Dorman 749-480

One Power Window Regulator (Regulator Only, Motor not Included).
Dorman Engineers assure that every product released to the market meets and often outperforms the original equipment specifications by analyzing the OEM parts & components for performance, fit and failure modes. With a focus on exacting precision, Dorman analyzes both original parts and individual components at the beginning of its design process. Dorman?s analysis establishes a complete product baseline that enables it to identify OE design flaws as opportunities for design improvements. Rigorous Quality Testing - The 3-dimensional coordinate measuring of the doors helps minimize the risk of damage to the replacement regulator by eliminating the need to alter the product during installation. No bending, twisting or adjusting is required; Dorman's Regulator achieves a perfect fit right out of the box. Tensile testing is used to evaluate individual elements of the part assembly (this test measures the strength of the cable and the amount of force needed to unsecure the cable from its mounting or for the cable to fray.) Extensive testing verifies that the correct material is being used for the application. If a material tests poorly, the Dorman Engineering team continues testing to determine if the failure is design or material related. They make the adjustments necessary to resolve the problem and provide a best in class product. Motor Dyno Testing certifies motor performance of original Window Regulator and Dorman's redesigned Window Regulator, and verifies that the original part meets or exceeds the declared horsepower rating and the Dorman part meets or exceeds our standards for performance. Cycle testing validates the durability and performance of every Dorman Regulator and Motor over extended cycles. Each and every Dorman Window Regulator is tested on a vehicle to ensure a trouble-free installation, excellent performance and operational durability. This real-life testing assists in creating step-by-step installation instructions, and gives insight into future product enhancements.
