Tired of Your Truck’s Electrical Gremlins?
Is your Silverado, Sierra, or SUV acting possessed? Flickering dashboard lights, power windows with a mind of their own, a security system that won’t cooperate, or worse—an intermittent no-start condition that leaves you stranded. These frustrating and unpredictable issues often point to one culprit: a failing Body Control Module (BCM). Instead of facing a costly trip to the dealership for diagnostics and programming, take control with our pre-programmed BCM solution, designed to get your truck back to its dependable self.
Common Symptoms & Your Solution
A faulty BCM can wreak havoc on your vehicle’s electronic systems. If you’re experiencing any of the following, this module is the definitive solution you’ve been looking for:
- Power windows, door locks, or mirrors operating intermittently or not at all.
- Interior or exterior lights staying on, flickering, or not turning on.
- The security system engaging randomly or preventing the engine from starting.

An Expert’s Insight on GM BCMs
As a technician with over two decades of experience, I’ve seen countless GMT900-platform trucks and SUVs come through the bay with bizarre electrical problems. The BCM is the central nervous system for the vehicle’s body electronics, and it’s susceptible to failure from voltage spikes, moisture, or simply age. Owners often waste hundreds on incorrect diagnoses, replacing switches and batteries first. The real fix is a properly programmed BCM. A junkyard unit won’t work because it’s coded to another vehicle’s VIN and options. Our service bridges that gap, providing a dealer-level programmed part directly to you. For a 2012-2013 Sierra 1500 BCM, this is the smartest, most reliable repair you can make.
Frequently Asked Questions
What exactly does the BCM do?
The Body Control Module (BCM) is a computer that supervises and controls many of your vehicle’s non-engine-related functions. This includes power windows, power locks, the alarm system, interior and exterior lighting, and the remote keyless entry system. When it fails, these systems can behave erratically.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship the module until we receive this information, as the programming is specific to your truck or SUV.
Will I need to do anything after installation?
In most cases, the module is a direct plug-and-play installation. However, as noted in our instructions, some vehicles may require a ‘Brake Pedal Position Relearn’ or an ‘Airbag System Sync’ using a professional scan tool if certain warning lights appear. This is highly dependent on the vehicle’s specific configuration.
Is this the correct BCM for my vehicle?
This BCM fits a wide range of 2012-2014 GM trucks and SUVs. Please check the fitment list on this page and verify that your old module has one of the compatible part numbers (22846365, 22737275, 22846364) to ensure a perfect match for your vehicle, such as the 2012-2013 Sierra 1500 BCM.
What if I have an airbag light after installing the BCM?
If the airbag warning light is on after installation, it means the new BCM needs to be synced with the vehicle’s airbag computer (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure, which requires a professional-grade diagnostic tool. Any competent repair shop can perform this quick procedure.
