Restore Full Functionality to Your HUMMER H2
If your 2008-2009 HUMMER H2 is plagued by bizarre electrical problems—from flickering lights and malfunctioning power windows to a security system that won’t cooperate or even a no-start condition—a failing Body Control Module (BCM) is the likely culprit. As the central nervous system for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating issues. This replacement BCM, part number 95151084, is the definitive solution to restore your truck’s proper operation and your peace of mind.
We take the guesswork and high dealership costs out of the equation. This isn’t just a part in a box; it’s a comprehensive solution. We utilize a professional Cloning Service, where we transfer the critical data from your original module to this replacement unit. This means the module arrives at your door pre-programmed with your vehicle’s specific VIN and configuration, making the installation process as close to plug-and-play as possible.
Case Study: A Tricky Diagnosis
I once had a 2008 HUMMER H2 in my bay with a classic case of electrical chaos. The customer reported intermittent radio failure, dome lights staying on, and the power locks working only half the time. A basic scan showed a slew of U-codes (communication errors), pointing to a network issue. After verifying the main power and ground circuits to the BCM were solid, we found evidence of minor water intrusion near the A-pillar, a common point of failure. The moisture had corroded several pins on the BCM connector, leading to internal damage. Replacing the faulty 2008-2009 HUMMER H2 BCM and repairing the connector pins solved every single symptom. This highlights how crucial a fully functional BCM is to the entire vehicle’s electronic ecosystem.
Signs of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lighting (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Malfunctioning security system, including random alarm activation or key fob issues.
- ✔ Instrument cluster warning lights (like the airbag light) illuminating without cause.
- ✔ Communication failure Diagnostic Trouble Codes (DTCs), often in the U-series (e.g., U0140, U0155).
- ✔ A complete no-start or no-crank condition where the engine does not respond.
Your Step-by-Step BCM Replacement Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2008-2009 HUMMER H2, the BCM is typically located on the left-hand (driver’s side) firewall, inside the cabin. You may need to remove lower dash panels for access.
- ✔ Disconnect and Remove: Carefully disconnect all electrical connectors from the old BCM. Note their orientation. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- ✔ Install the New Module: Mount your new, pre-programmed BCM onto the bracket and securely reconnect all electrical connectors.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Verify Operation: Start the vehicle and test all body functions: lights, locks, windows, radio, etc. Address any post-installation procedures as noted below if warning lights appear.
Important Post-Installation Information
While our cloning service handles the primary programming, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Disclaimer: These procedures can vary. Always refer to a factory service manual for your specific vehicle or consult a certified technician.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After your purchase, you will send us your original BCM. We use specialized equipment to extract the vehicle-specific data and transfer it directly to the replacement module. This ensures compatibility with your existing keys and vehicle options.
Why do you need my VIN?
We use your Vehicle Identification Number (VIN) to access the latest GM software updates for your specific vehicle build. This ensures the BCM we send you has the most current and stable programming available.
Do I need to send my original BCM to you?
Yes, for our cloning service, we require your original module to transfer the necessary data. We will return your original module along with the newly programmed replacement.
Is this a difficult part for a DIYer to install?
For someone with basic mechanical skills, the replacement is straightforward. The main challenge is typically accessing the module’s location behind the dash. Our cloning service eliminates the need for any programming, which is the most difficult part of the job.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag’s Supplemental Inflatable Restraint (SIR) module. This requires a ‘Setup SDM Primary Key’ procedure with a bidirectional scan tool, which a professional mechanic can perform.
