Restore Full Function to Your GM Vehicle
Are you battling frustrating and unpredictable electrical problems? Flickering dashboard lights, power windows with a mind of their own, intermittent starting issues, or security system faults can all point to a single failing component: the Body Control Module (BCM). This vital computer is the central hub for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing issues. This is your direct, plug-and-play solution to restore order and get your vehicle operating reliably again.
Common Symptoms & Your Solution
A failing BCM can be difficult to diagnose, often mimicking other problems. If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior or exterior lights staying on, flickering, or not turning on.
- The security system acting erratically or preventing the car from starting.
- Dashboard warning lights appearing for no reason.
- Erratic gauge behavior on the instrument cluster.
- Communication issues with diagnostic scan tools.

Expert Insight: The Brain of Your Vehicle’s Comfort & Convenience
Think of the BCM as the middle manager for your car’s electronics. It takes commands from switches (like your window or lock buttons) and sends signals to the motors and lights to make them work. Over years of heat cycles, vibrations, and voltage fluctuations, the delicate circuits inside can degrade, causing bizarre, ghost-in-the-machine problems. Simply swapping in a used BCM won’t work, as it’s coded to another vehicle’s specific options and security key. Our service of providing a professionally programmed GM body control module is the most efficient and cost-effective path to a lasting repair, saving you hundreds in dealership diagnostic and programming fees.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, door locks, interior and exterior lighting, the alarm system, and instrument panel gauges.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to program the module specifically for your vehicle’s factory options before we ship it to you.
Is this part difficult to install?
For someone with basic mechanical skills, installation is typically straightforward. The BCM is usually located under the dashboard on the driver’s or passenger’s side. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. However, we always recommend consulting a service manual for your specific vehicle.
Do I need to send you my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after installation?
On some models, the new BCM may need to be synced with the airbag system (SDM). If the airbag light appears, a technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync that resolves the light.
Will this fix my specific problem?
This programmed GM body control module is a direct solution for the symptoms listed. If your vehicle has been properly diagnosed with a faulty BCM, this part will resolve those issues and restore proper function.
