End Frustrating Electrical Problems in Your GM Truck
Are strange electrical issues making your GMC Sierra, Chevrolet Silverado, or Tahoe unreliable? When power windows, door locks, the security system, or the HVAC system start acting up intermittently, a failing Body Control Module (BCM) is the most common cause.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that acts as a central hub for controlling “body” electronics. This includes functions not related to the engine, such as power windows, door locks, interior and exterior lighting, wipers, the security system, and the HVAC (climate control) system.
Is this BCM truly plug-and-play?
Yes. We pre-program the module to your vehicle’s specific VIN before it ships. This ensures it communicates correctly with your truck’s other systems upon installation, eliminating the need for a trip to the dealership for expensive programming.
My airbag light is on with code B1001. Will this fix it?
This BCM will resolve the communication fault causing the B1001 code. However, after installation, you may need to perform a “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool to sync the new BCM with the airbag system and turn off the warning light.
Where is the BCM located on my 2009 Sierra 2500?
On most 2007-2013 GM trucks and SUVs, including the Sierra and Silverado, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module without any extra fees or hassle.
What if I still have problems after installation?
