Is Your HUMMER H2 Plagued by Bizarre Electrical Issues?
When the complex electronic systems in your 2003-2007 HUMMER H2 start to fail, it can be incredibly frustrating. One moment the power windows work, the next they don’t.

The Body Control Module (BCM) is the central command for these systems, and when it fails, it can cause a cascade of unpredictable problems. It’s time to stop chasing symptoms and fix the root cause with a reliable, pre-programmed solution.

Frequently Asked Questions
What does a Body Control Module do on a HUMMER H2?
The BCM acts as the central hub for your H2’s body electronics. It manages non-engine related functions like interior and exterior lighting, power windows and locks, the security system, wipers, and the HVAC climate control system, ensuring they all work together seamlessly.
Is this BCM truly plug-and-play?
Yes. We program the module to your vehicle’s specific VIN before shipping. This ensures it’s ready for installation right out of the box with no additional programming or dealership intervention required for most functions.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and expense of return shipping.
What if my airbag light stays on after installation?
In some cases, an airbag light may remain on after installation. This typically requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a qualified technician with a professional-grade scan tool to sync the new BCM with the airbag system.
Where is the BCM located on a 2003-2007 HUMMER H2?
On the HUMMER H2, the HUMMER H2 Body Control Module is typically located on the left-hand (driver’s) side of the dash, often under or near the steering column.
