Restore Full Functionality to Your GM Vehicle’s Electronics
Are you battling bizarre electrical problems in your GM car, truck, or SUV? A faulty Body Control Module (BCM) is often the culprit behind these frustrating issues. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from the interior lights and power windows to the security system. When it fails, it can cause a cascade of seemingly unrelated problems, making diagnosis a nightmare. This replacement Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
Common Symptoms of a Failing GM BCM
If you’re experiencing any of the following, a failing BCM is the likely cause:
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ False warning lights on the instrument cluster (e.g., “Service Theft System”).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers not functioning properly or activating on their own.
- ✔ Significant battery drain when the vehicle is off.

Post-Installation Information
While this module is delivered ready for installation, some vehicles may require a final sync procedure for certain systems. For example, if the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary on some models to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
How does the VIN programming work?
After you place your order, you provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this number to access the official GM database and load the exact software and calibration files your vehicle requires onto the BCM before shipping it.
Do I need to send my old BCM back?
No. This part has no core charge. You can keep your original module, which saves you the time and expense of a core return.
Will this fix all my car’s electrical problems?
This module will correct any issues directly caused by a failing BCM. If your problems are due to faulty wiring, sensors, or other components, those will still need to be addressed separately. A proper diagnosis is always recommended.
What tools are needed for installation?
Installation typically requires basic hand tools like a socket set and screwdrivers to access the BCM, which is usually located under the dash. While the part is plug-in, some models may require post-installation procedures with a professional scan tool as noted.
What if my airbag light comes on after installation?
This is a known possibility on some GM models. It means the new BCM needs to be synced with the airbag system’s SDM. A repair shop with a high-level diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part that has been electronically restored to factory specifications with the latest software for your vehicle.
