Are you battling frustrating electrical issues in your Hummer H2 or other GM truck/SUV? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can cause a wide range of confusing and intermittent problems. This OEM-quality replacement BCM, part number 15064149, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play installation.
Is Your GM Vehicle Showing Signs of BCM Failure?
A faulty BCM can manifest in numerous ways. Look out for these common symptoms, which often indicate the module is the root cause of your electrical problems:
- ✔ Unresponsive or erratic power windows, door locks, or interior lights.
- ✔ HVAC system failure, including a blower motor that won’t turn on or can’t be controlled.
- ✔ An illuminated airbag warning light, often accompanied by DTC B1001.
- ✔ Security system malfunctions, leading to no-start or crank-no-start conditions.
- ✔ Wipers that operate intermittently or not at all.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs).

Installation & Post-Install Notes
The BCM is typically located under the steering column on the driver’s side. Installation involves disconnecting the battery and swapping the electrical connectors from the old module to the new one. In most cases, the vehicle will start and function correctly immediately. However, please be aware of these potential post-installation procedures:
- Airbag System Sync: If the 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Frequently Asked Questions
What does this Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this part ready to install out of the box?
Yes! We pre-program the module to your vehicle’s VIN before it ships. This makes it a plug-and-play part, requiring no additional programming from a dealer.
What if my airbag light is on after I install this?
This is a known possibility. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A repair shop with a high-level scan tool can perform the ‘Setup SDM Primary Key’ procedure to resolve this.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep or dispose of your original module without any extra fees.
