Restore Full Electronic Functionality to Your GM Vehicle
Are you battling frustrating electrical issues in your GMC Yukon, Chevy Silverado, or Tahoe? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). This vital component acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a cascade of seemingly unrelated problems. This OEM-quality BCM, interchangeable with part number 15064149 and 15116066, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play installation.
Symptoms of a Failing BCM
- ✔ Unresponsive or intermittent HVAC controls, including the blower fan.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Erratic interior or exterior lighting behavior.
- ✔ An illuminated airbag light, often with a B1001 diagnostic trouble code.
- ✔ Security system faults, leading to no-start or crank-no-start conditions.
- ✔ False warnings on the instrument cluster.

Installation and Post-Install Notes
Installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before swapping the module is recommended. In most cases, the process takes less than 15 minutes. After installation, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light is on, or a ‘Brake Pedal Position Relearn’. These procedures require a professional-grade scan tool. Best of all, there is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does this Body Control Module do?
The BCM is a computer that manages and controls your vehicle’s non-engine related functions. This includes power windows, door locks, the security system, lighting, wipers, and the HVAC system.
Is this module ready to install out of the box?
Yes! This BCM comes pre-programmed to your vehicle’s specific VIN. This ensures it communicates correctly with your vehicle’s other modules for a simple, plug-and-play installation.
What if my airbag light stays on after I install it?
If the airbag light is on, it means 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 using a professional scan tool.
Do I need to return my old BCM?
No. We do not require a core return for this part. You can keep your old module without any additional charges or hassle.
How can I be sure the BCM is my problem?
A faulty BCM often causes multiple, seemingly unrelated electrical issues. If your power locks, windows, and HVAC are all acting up, the BCM is a likely culprit. A full vehicle scan with a professional tool can help confirm by showing communication codes.
Will this fit my 2004 Chevy Silverado?
Yes, this module fits a wide range of 2002-2007 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Escalade, and Hummer H2. Please check the detailed fitment list on this page to confirm for your specific model and year.
