Detailed Description

Designed for 2007-2008 Kia Rondo rear left and 2009 Kia Rondo rear left applications, this Dorman 748-426 assembly replaces the original power window regulator and motor with a unit built to match the factory configuration.

• Slow, uneven, or noisy window operation
• Failed window motor or worn regulator components
