Window stuck down or not moving smoothly? This electric window regulator assembly is for the front passenger (right) side. It fits Chevy Cobalt (2005-2010), Pontiac G5 (2007-2010), and Saturn Ion (2003-2007). The unit includes the regulator and motor—ready to bolt in. Replaces part numbers like 19301977, 15899050, 751015, and others. Installation is pretty straightforward if you're comfortable with door panel removal and basic wiring connections. Just disconnect the battery first for safety. A direct OE-style replacement to get your window working quietly and reliably again. Always double-check your vehicle's year and model before ordering!
