Are you battling frustrating electrical problems in your GM vehicle? Issues like erratic power windows, malfunctioning door locks, a misbehaving security system, or interior lights with a mind of their own often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it falters, it can cause a cascade of confusing and unpredictable symptoms. This replacement Body Control Module is the definitive solution to restore full functionality and peace of mind.
This isn’t just a part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This critical step ensures seamless integration with your vehicle’s existing systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, delivering a true plug-and-play component.
From the Diagnostic Bay
We had a 2011 Acadia come in with a truly bizarre complaint: the radio would randomly change stations, and the rear wiper would activate every time the driver used the left turn signal. The customer had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication error codes pointing to the BCM. Instead of hours of chasing wires, we installed a VIN-programmed BCM. In under an hour, all the strange electrical gremlins were gone, and the vehicle was operating perfectly. It’s a classic case of how a faulty BCM can manifest in the strangest ways.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic or inoperative interior and exterior lighting.
- ✔ Security system faults or the vehicle not starting due to security lockout.
- ✔ Dashboard warning lights appearing randomly.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Communication errors with other vehicle modules (DTC U-codes).

Installation and Post-Install Notes
While installation is straightforward, some vehicles may require additional calibration steps after the new BCM is installed. These are known as ‘relearn’ procedures and can sometimes be completed by a DIYer, but may require a professional scan tool.
- Airbag System Sync: 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. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s electronic accessories and convenience features, such as power windows, locks, lights, wipers, security system, and more.
Do I need to program this module?
No. We program the module to your vehicle’s VIN before we ship it to you. This makes the installation process much simpler and saves you a trip to the dealership. Please provide your VIN at checkout.
What if my airbag light comes on after I install it?
This is a possibility. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module without needing to send it back.
How do I know if this BCM will fit my vehicle?
This module fits a wide range of GM vehicles, including the 2008-2012 Buick Enclave, Acadia, Traverse, various Express/Savana vans, Impala, and more. The best way to ensure compatibility is to match the part number from your original BCM to the list of compatible numbers on this page.
