Obaee Rear Right Window Regulator with Motor for Hummer H2 (2003–2009) — OE Fit, Pre‑assembled 2‑Pin Connector

This Obaee rear right (passenger-side) window regulator with motor is a direct OE-fit replacement for Hummer H2 models and restores powered window function without splicing or major modification.

If your Hummer H2 (2003–2009) has a rear passenger window that moves slowly, binds, or won’t respond to the switch, the problem is often the regulator assembly. The Obaee unit is designed to replace OE part numbers 751-708, 42-187C, 135-01903R, 42187C, 13501903R and 15771354. It includes the motor and mounts to the factory location, helping you get the window operating again with a straightforward swap.

How does this Obaee assembly match my Hummer’s original part?

The Obaee regulator is engineered to fit the same mounting points, cable routing, and electrical connector style as the factory component. It’s intended to be a like-for-like replacement so the window aligns and seals correctly when installed.

• Direct fit for Hummer H2 model years 2003–2009.
• Replaces OE numbers 751-708 and compatible equivalents.
• Two-pin motor connector matching factory harness.
• Pre-assembled regulator and motor for straightforward swap.

What should I expect during installation?

Installation is designed to be user-friendly for technicians and competent DIYers: no wire splicing or major door modifications are necessary. Removing the door panel, transferring any trim clips, bolting the assembly in place and reconnecting the two-pin connector are the typical steps.

• No wiring modification required; plugs into existing harness.
• Mounting holes and linkage align with OEM locations.
• Works with factory window glass and guides.
• Recommended to use basic hand tools and a second hand to support the glass.

Will this part improve a window that’s slow or noisy?

When the original regulator or motor is worn, windows can hesitate, bind, or create grinding sounds. Replacing the entire assembly with the Obaee unit eliminates worn cables and gear components that frequently cause those symptoms, often returning smoother, quieter operation.

• New motor and cable components reduce bind and noise.
• Restores consistent movement and proper glass alignment.
• Helps window seals meet evenly to reduce wind noise.
• Can prevent further wear on window tracks and switches.

Who is this for?

It’s suitable for independent mechanics, body shops, and confident DIY installers who want an assembled unit that plugs into the factory connector, mounts in the original location, and replaces the listed OE numbers.
