Is Your GM Vehicle Acting Possessed?
Are you dealing with a frustrating array of electrical gremlins in your Chevrolet, GMC, Cadillac, or Buick? Flickering lights, malfunctioning power windows or locks, a security system that won’t cooperate, or random warning lights on your dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause unpredictable and annoying problems. Don’t let a faulty computer dictate your driving experience. This VIN-programmed GM Body Control Module is the reliable, straightforward solution you need.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system faults or starter disable issues.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Problems with the heating and A/C blower motor controls.

Post-Installation Information
While this module is designed for a simple installation, some vehicles may require a couple of minor relearn procedures after the BCM is installed. These are typically straightforward and can sometimes be required to ensure all systems communicate correctly.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper function of the brake lights and traction control system.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, security system, wipers, and climate controls.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Is this BCM ready to install when I receive it?
Yes! This is the key benefit of our service. We pre-program the module to your vehicle’s specific VIN before shipping, so it’s ready for installation without needing a trip to the dealer for programming.
Where is the BCM located on my vehicle?
The location varies by model. Common locations include behind the dashboard (often on the driver’s side near the steering column), under the center dash, or behind the glove box. Your service manual will show the exact location.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Will this fix all of my vehicle’s electrical problems?
A faulty BCM is the cause of many common electrical issues. If your symptoms match the ones listed, there is a very high probability this will solve the problem. However, we always recommend proper diagnostics to confirm the BCM is the root cause before ordering.
