Is Your GM Truck or Van Plagued with Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows or locks, erratic gauges, or a security system that has a mind of its own, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated issues. This VIN-programmed BCM is the direct, reliable solution to restore full functionality to your vehicle.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or seats not working or working erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ Horn sounding unexpectedly or not working.
- ✔ Inoperative remote keyless entry (RKE) system.
- ✔ Security or anti-theft light staying illuminated, preventing the vehicle from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ False warnings on the driver information center (e.g., “Service 4WD”).

Important Post-Installation Information
While this BCM is pre-programmed for a straightforward installation, some vehicle systems may require a ‘handshake’ with the new module. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance. There is no core charge for this part.
Frequently Asked Questions
What does the BCM actually do on my truck?
The Body Control Module (BCM) acts as the main computer for your vehicle’s comfort and convenience features. It controls the power windows, locks, interior/exterior lights, security system, wipers, and more.
Is this BCM difficult to install?
The physical installation is straightforward. For most trucks like the Silverado and Sierra, it’s located under the steering column. For vans like the Express and Savana, it’s in the center of the dash. Since we program it to your VIN, no initial programming is needed, but some minor relearn procedures may be required post-installation as noted.
Do I have to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What happens if I forget to provide my VIN?
We cannot ship your order without your vehicle’s VIN. The programming service is essential for the module to function correctly in your vehicle. We will contact you to retrieve the VIN before we can process and ship your BCM.
Will this fix my airbag light?
If the BCM is the cause of the airbag light, this will resolve the issue. However, after installation, the airbag system (SDM) must be synced with the new BCM using a professional diagnostic tool to turn off the light.
