We pre-program it to your vehicle’s specific VIN, ensuring it arrives ready for a fast, plug-and-play installation, getting you back on the road without a costly trip to the dealership.
Common Symptoms & Your Solution
A faulty BCM is the hidden culprit behind many perplexing electrical issues. If you’re experiencing any of the following, this module is your fix:
- Power Feature Failure: Intermittent or non-working power windows, door locks, or interior/exterior lights.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer in your vehicle that controls and monitors most of the non-engine-related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, you often see strange, unrelated electrical problems.
Is this part difficult to install?
For most DIYers, the installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. It’s usually held in by a few clips or bolts and has several electrical connectors. The physical swap can often be done in 5-15 minutes.
Do I need to take my truck to the dealership after installing this?
No. The primary benefit of our module is that we program it to your vehicle’s VIN *before* it ships. This means it’s ready to be installed and function correctly without any additional programming from a dealer or mechanic, saving you hundreds of dollars.
What if my airbag light is on after installation?
In some cases, particularly if DTC B1001 was present, the new BCM needs to be synced with the airbag system’s computer (SDM). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed with a professional-grade scan tool. It is the only post-installation procedure that might be required.
Is there a core charge for my old part?
No, there is no core charge. You can keep, discard, or recycle your old module without any penalty or need to return it to us. We make the process as simple as possible.
Will this fix my specific electrical problem?
This 2007-2011 Sierra 1500 Body Control Module is the solution for a vast majority of the common electrical issues listed above. If your vehicle’s symptoms match the ones described, it is highly likely that a faulty BCM is the cause and this part is the correct fix.
