Tired of Unpredictable Electrical Problems in Your Hummer H2?
If you’re dealing with a frustrating array of electrical issues in your 2003-2007 HUMMER H2, a failing Body Control Module (BCM) is the most likely culprit. As the central command for your vehicle’s body electronics, a faulty BCM can cause chaos, from non-working power windows and erratic climate controls to a vehicle that won’t even start. This isn’t just an annoyance; it’s a reliability issue. This replacement BCM, equivalent to part number 10367690, is the definitive solution to restore your H2’s functionality and your peace of mind.
The biggest advantage? We handle the programming for you. Simply provide your vehicle’s VIN during checkout, and we’ll flash the module with the latest GM software specific to your HUMMER H2. This means no expensive trip to the dealership for programming. It arrives at your door ready for a true plug-and-play installation, getting you back on the road in minutes, not days.
A Technician’s Notebook
I recently had a 2005 HUMMER H2 in the bay that was a diagnostic nightmare. The owner reported the radio would turn on by itself, the driver’s side power window worked intermittently, and the security light would flash, causing a no-start condition. A basic scan showed a dozen communication codes. After checking the main grounds and power feeds, all signs pointed to the BCM. These modules, especially on the GMT800 platform, are notorious for internal circuit board failures. We installed one of our pre-programmed modules, and every single issue was resolved instantly. The customer saved hundreds by avoiding dealer programming fees and diagnostic time.
Is Your Hummer H2 Showing These Symptoms?
- ✔ The security or anti-theft system acts up, preventing the engine from starting.
- ✔ Power windows, door locks, or interior lights work sporadically or not at all.
- ✔ The HVAC system is unresponsive, or the blower motor won’t turn on.
- ✔ Your scan tool shows communication DTCs or a specific airbag code like B1001.
- ✔ The instrument cluster lights flicker or warning lamps stay illuminated for no reason.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the Module: On the HUMMER H2, the BCM is typically found on the left-hand side of the dash, accessible from underneath the steering column.
- ✔ Swap the Part: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Remove any mounting bolts or clips holding it in place, then install the new module.
- ✔ Reconnect and Test: Re-attach the electrical connectors to the new BCM, ensuring they click securely into place. Reconnect the battery terminal.
- ✔ Final Checks: Start the vehicle and test all body functions—lights, windows, locks, wipers, and HVAC. In most cases, the repair is complete. For potential airbag light issues, see our FAQ below.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes the installation plug-and-play, saving you time and money.
Why is my airbag light on after installing the new BCM?
Occasionally, the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This is only necessary if the airbag light appears after installation.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module without any extra fees or the hassle of returning it.
What tools do I need for installation?
Basic hand tools are typically all that’s required, such as a socket set to disconnect the battery and potentially remove a few trim panels or mounting bolts. The installation itself is very straightforward.
Will I need to perform any other procedures after installation?
Besides the potential airbag sync, some models may require a Brake Pedal Position (BPP) sensor relearn to ensure proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific requirements.
