Restore Full Functionality to Your HUMMER H2
Is your 2008-2009 HUMMER H2 experiencing bizarre electrical issues? Flickering lights, malfunctioning power windows, intermittent door locks, or strange warning chimes are common signs of a failing Body Control Module (BCM).

This replacement Body Control Module, part number 25934763, is the definitive solution to restore your H2’s electrical systems to perfect working order.

Simply provide us with your VIN after purchase, and our technicians will flash the module with the latest GM software updates, ensuring seamless integration and optimal performance. This plug-and-play approach saves you time, money, and the headache of a trip to the dealer.
From the Diagnostic Bay
A customer brought in their ’09 H2 with a list of complaints that sounded like the vehicle was haunted. The dome lights would stay on, the radio would randomly change stations, and the power locks had a mind of their own. After checking fuses and wiring, all signs pointed to the BCM. Instead of a costly dealer visit, we installed one of our VIN-programmed modules. The installation was straightforward, and upon starting the vehicle, every single issue was gone. The customer was thrilled to have their truck back to normal without the typical hassle and expense. This is the simple, effective fix your H2 needs.

The Importance of VIN Programming
The Body Control Module is not a one-size-fits-all part. It is specifically calibrated to the unique features and options of your HUMMER H2. Our mandatory VIN programming service ensures that the replacement BCM you receive is a perfect match for your vehicle’s configuration. This critical step ensures that all systems—from the power seats to the climate control—function exactly as they did from the factory. By handling the programming before shipment, we provide a reliable component that is ready for installation right out of the box.
Installation and Post-Install Notes
This BCM is located on the left-hand side of the firewall in your 2008-2009 HUMMER H2. While the physical swap is straightforward for a knowledgeable DIYer or any professional technician, please be aware of potential post-installation procedures. Depending on your vehicle’s specific systems, additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the modules.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related functions. This includes power windows, door locks, interior and exterior lighting, security systems, wipers, and various other comfort and convenience features.
Is this module difficult to install?
For someone with automotive repair experience, the physical installation is typically straightforward. However, due to its critical role and the potential need for post-install relearn procedures (like for the airbag or brake systems), we recommend installation by a qualified technician.
Do I need to have this BCM programmed by a dealer?
No. That’s the primary benefit of our service. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready to be installed, saving you from expensive dealership programming fees.
Where is the BCM located on my 2008-2009 HUMMER H2?
The Body Control Module on the 2008-2009 HUMMER H2 is located on the left-hand (driver’s side) of the firewall, inside the cabin.
What happens if I forget to provide my VIN?
Providing your VIN is a required step for purchase. We cannot ship the module without it, as the programming is essential for the part to function correctly in your vehicle. Our team will contact you if the VIN is not provided with the order.
