Obaee Window Regulator with Motor - Rear Left Driver Side for Hummer H2 2003-2009, Direct-Fit Pre-Assembled

Obaee's complete rear left (driver-side) window regulator with motor is a direct-fit replacement for Hummer H2 models and restores power-window function without cutting or splicing wires.

If your Hummer H2 (2003–2009) rear driver-side window is slow, stuck, or won't move at all, this Obaee assembly replaces the entire regulator and motor using OEM-style mounting points and the same electrical connector. It’s supplied as a ready-to-install unit that targets common failure points: worn cables, stripped gears, and burned-out motors. The part cross-references OE numbers 751-707, 715771355, HU1550100, and 135-01904L so you can confirm fitment quickly.

How does this Obaee regulator fit my Hummer H2?

The Obaee assembly is engineered to match the original regulator’s bolt pattern and electrical plug for a straightforward replacement. No vehicle wiring modifications are required—simply unbolt the old assembly, swap the connector, and fasten the new part. This reduces install time and risk of wiring faults.

• Direct-fit for Hummer H2 years 2003–2009
• Replaces OE part numbers 751-707 and equivalents
• Two-pin motor connector matches original harness
• Mounting points align with factory holes—no drilling

What components come with the replacement and what wear issues does it address?

This kit includes the regulator rail, cables, and the motor pre-assembled so you get a complete mechanism rather than piecing together parts. It resolves failures caused by frayed cables, stripped sprockets, or failed motors that commonly make windows jam or fall inside the door. Using a full assembly helps prevent repeat repairs from overlooked subcomponents.

• Pre-assembled regulator track and motor for quick swap
• Replaces both mechanical and electrical failure points
• Eliminates risky temporary fixes like cable splicing
• Manufactured to match factory travel and tension specs

How long does installation take and will I need special tools?

A competent DIYer or an experienced technician can typically complete the swap in 60–120 minutes depending on door trim complexity. Common hand tools and a basic socket set are usually sufficient; the motor uses the factory two-pin connector so no soldering or harness modification is required. Always follow vehicle-specific door panel removal steps to avoid breaking clips.

• Estimated install time: about 1–2 hours
• Required tools: screwdrivers, panel pry tool, socket set
• No wire splicing or custom wiring needed
• Instructions: remove door panel, unbolt old assembly, install Obaee unit

Will this replacement last and what support does Obaee provide?

The part is built to meet the mechanical tolerances of OE regulators and uses a sealed motor housing to protect internal gears. While life expectancy depends on usage and environmental conditions, replacing the full assembly reduces the chance of early secondary failures. Obaee also offers customer support if you encounter functional issues after installation.

• Engineered to OE mounting and travel specifications
• Motor sealed to resist moisture and debris
• Includes manufacturer support for post-sale concerns
• Recommended inspection: check window tracks and seals during install

Who this is for: Hummer H2 owners and independent mechanics looking for a straightforward, OEM-replacement style rear left (driver-side) window regulator with motor. Ideal if you want a complete, plug-and-play swap for OE numbers 751-707, 715771355, HU1550100, or 135-01904L to restore reliable power-window operation without cutting factory wiring.
