Restore Full Electrical Function to Your Hummer H2
Are you battling frustrating electrical problems in your 2003-2007 Hummer H2? A faulty Body Control Module (BCM) is often the culprit behind a host of issues, from malfunctioning lights and power windows to erratic HVAC behavior and even no-start conditions. The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of seemingly unrelated problems. This OEM-quality replacement module, part number 10383536, is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation.
From the Diagnostic Bay
We had a 2005 Hummer H2 come in with a classic case of electrical gremlins. The owner had already replaced the battery twice and the alternator once, convinced he had a charging system issue. The dash lights would flicker, the radio would cut out, and sometimes the power locks wouldn’t respond. After a quick scan, we saw multiple communication DTCs pointing to the BCM. The original module was causing a parasitic drain and disrupting the entire data network. We installed one of our VIN-programmed BCMs, and within 10 minutes, every single issue was resolved. It’s a reminder that what seems like a major electrical failure is often a single, straightforward component replacement.
Common Symptoms of a Failing Hummer H2 Body Control Module
If you’re experiencing any of the following, a failing BCM is the likely cause. Replacing it can save you hours of diagnostic time and prevent further component damage.
- ✔ Non-responsive or intermittently working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ HVAC and climate control systems that blow air at the wrong speed or won’t function.
- ✔ An active airbag warning light, often accompanied by DTC B1001.
- ✔ Security system malfunctions, including false alarms or the inability to start the vehicle.
- ✔ Inaccurate gauge readings or warning messages on the instrument cluster.
Plug-and-Play Solution with VIN Programming
Forget expensive dealership visits and programming fees. We pre-program this module to your Hummer’s specific Vehicle Identification Number (VIN) before shipping. This ensures it communicates flawlessly with your vehicle’s other electronic systems right out of the box. The process is simple: place your order, provide your VIN, and we handle the rest. Your new BCM will arrive ready for a quick, hassle-free installation.
Installation is straightforward: The BCM is typically located on the left-hand side of the dash. Simply disconnect the vehicle’s battery, remove the old module, plug in the new one, and reconnect the battery. In most cases, the vehicle will start and run perfectly. However, for some vehicles, a post-installation procedure may be needed.
Post-Installation Notes: If your airbag light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool. This syncs the new BCM with the airbag system. This is not required for all vehicles but is a known possibility.

Frequently Asked Questions
What does the Body Control Module do on my Hummer H2?
The BCM is a computer that controls nearly all non-engine related electronics in your H2. This includes the power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC blower functions.
Is this part ready to install when I receive it?
Yes! This module is fully programmed to your vehicle’s VIN before it ships. This makes the installation plug-and-play, with no need for an expensive trip to the dealership for programming.
What if my airbag light is on after I install the new BCM?
In some cases, the new BCM needs to be electronically introduced to the airbag system (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure which requires a professional-grade scan tool. This will resolve the airbag light issue.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep or dispose of your old module without any hassle.
Where is the BCM located on a 2003-2007 Hummer H2?
The Body Control Module on the Hummer H2 is located behind the dashboard on the driver’s side, to the left of the steering column.
