End the Electrical Frustration in Your HUMMER H2
If you’re dealing with baffling electrical issues in your 2003-2007 HUMMER H2—like flickering lights, a temperamental security system, or accessories that work one minute and not the next—you’ve likely met the common culprit: a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics. When it fails, it can create a cascade of problems that are frustrating to diagnose and even more frustrating to live with. This replacement BCM, part number 15137394, is the definitive solution to restore order and reliability to your vehicle.
Our unique Cloning Service makes this repair easier and more affordable than ever. Forget about costly dealership visits for programming. Simply send us your original BCM, and we will professionally transfer all the essential data—including your vehicle’s VIN and specific options—to this replacement unit. The module you receive will be a true plug-and-play solution, ready for immediate installation and operation, getting your H2 back to perfect working order without any extra steps.
A Technician’s Notebook: The H2 with a Mind of Its Own
I’ll never forget a 2006 H2 that rolled into my bay. The owner was at his wit’s end. The alarm would go off randomly, the power locks were unresponsive, and the HVAC blower motor had a mind of its own. He’d already replaced the battery and checked the main grounds. After hooking up my scan tool, I saw a slew of communication and body-related DTCs, including the infamous B1001. In my 20+ years of experience, these ghost-in-the-machine symptoms on GM trucks and SUVs almost always point to the BCM. The internal circuit boards develop micro-fractures over time from heat cycles and vibration, leading to intermittent connections. We swapped in a cloned BCM, and just like that, every single issue was resolved. It’s a testament to how critical this single component is to the vehicle’s entire electronic ecosystem.
Is Your H2 Exhibiting These Electrical Faults?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution for your 2003-2007 HUMMER H2 BCM problems:
- âś” Unresponsive or erratic power windows, door locks, or mirrors.
- âś” Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- âś” The security system malfunctioning, causing no-start conditions or random alarms.
- âś” HVAC controls not working or the blower motor operating intermittently.
- âś” An airbag warning light on the dash, often accompanied by DTC B1001 (Option Configuration Error).
- âś” A battery that drains overnight for no apparent reason (parasitic draw).
- âś” Communication errors with other modules on the vehicle’s network.
A Straightforward Guide to Installation
You don’t need to be a master mechanic to install this part. The process is quick and requires only basic tools. Our cloning service ensures there’s no complex computer work needed on your end.
- Safety First: Always begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On the HUMMER H2, the Body Control Module is typically found on the left-hand (driver’s) side of the dashboard, under the steering column area.
- Swap the Module: Carefully unplug the electrical connectors from your old BCM. Remove any mounting bolts or clips holding it in place. Install the new module, secure it, and firmly reconnect all electrical connectors.
- Power Up: Reconnect the negative battery terminal. The vehicle will now power up with the new BCM fully operational.
- Perform Final Checks: Test all body functions (lights, locks, windows, etc.). In some cases, a post-install procedure like an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be needed if related warning lights appear. This can be done with a capable bi-directional scan tool.

Frequently Asked Questions
What exactly is a BCM cloning service?
Our cloning service is a process where we transfer the vehicle-specific software and security data from your original BCM to the replacement unit. This makes the new module a 100% plug-and-play part, eliminating the need for expensive dealership programming.
Will I need to go to the dealer after installing this?
No. Because we clone your original module’s data, this part will not require any additional programming from a dealership, saving you time and money.
My airbag light is on after installation. What should I do?
If the airbag light appears, it means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old BCM?
No, there is no core charge. We require your original module to perform the cloning service, and it will be returned to you along with your newly programmed replacement unit.
How do I know this will fix my 2003-2007 HUMMER H2 BCM issues?
If your vehicle is experiencing multiple, seemingly unrelated electrical body faults as listed in the symptoms section, a failing BCM is the most common cause. This part is designed to be a direct, reliable solution for those specific failures.
