Is your 2008-2009 Hummer H2 experiencing a host of bizarre electrical issues? From flickering lights and malfunctioning power windows to a security system that has a mind of its own, these are classic signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it starts to fail, it can make driving your H2 a frustrating experience. Restore full functionality and reliability with our pre-programmed BCM, designed to be a direct-fit replacement for your vehicle.
This isn’t just a part in a box. We take the hassle out of the repair by programming this module specifically to your Hummer’s Vehicle Identification Number (VIN) before it ships. This critical step ensures that the BCM communicates correctly with your vehicle’s other systems, saving you a costly trip to the dealership for programming. Simply provide your VIN at checkout, and we’ll handle the rest, sending you a part that’s ready for installation.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing intermittently.
- ✔ The instrument cluster displaying incorrect information or warning lights.
- ✔ ‘No Communication’ errors when scanning with a diagnostic tool.
- ✔ Unexplained battery drain when the vehicle is off.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process much simpler and saves you from extra dealership fees.
Where is the BCM located on my 2008-2009 Hummer H2?
The Body Control Module on the 2008-2009 Hummer H2 is located on the left-hand (driver’s side) of the firewall, inside the cabin.
What if my airbag light comes on after installation?
This is a possibility. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
Will this fix my power window and lock problems?
If the BCM is the root cause of the failure, then yes. The BCM directly controls these functions, and replacing a faulty unit is the correct repair for these common electrical symptoms.
