Restore Full Electrical Function to Your GM Vehicle
Are you battling a host of bizarre and frustrating electrical problems in your Chevy Express or other GM vehicle? Intermittent power windows, malfunctioning door locks, erratic interior or exterior lights, and false security system alarms are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can make your vehicle unreliable and difficult to operate. This replacement Body Control Module is the definitive solution, arriving at your door pre-programmed to your vehicle’s specific VIN, ensuring a seamless and straightforward installation.
From the Diagnostic Bay
We recently had a 2011 Express 3500 work van from a local plumbing company towed in. The driver’s complaint was a dead battery every morning and power locks that seemed to have a mind of their own, locking and unlocking randomly. After checking the battery and alternator, our diagnostics pointed directly to an internal fault in the BCM causing a parasitic draw. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-matched units. The van was back in service the same afternoon, with all electrical gremlins banished and no more dead batteries. It’s a common failure, but with the right part, it’s a simple fix.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operate erratically or not at all.
- ✔ Interior dome lights or exterior lights stay on, flicker, or won’t turn on.
- ✔ The security system or alarm engages randomly or shows a fault message.
- ✔ Dashboard warning lights appear for seemingly unrelated systems.
- ✔ The horn honks unexpectedly.
- ✔ Issues with the radio or climate control functions.
- ✔ Unexplained battery drain leading to a no-start condition.

Installation and Post-Install Considerations
While this module is designed for plug-and-play installation, certain vehicle systems may require a recalibration or sync procedure after the new BCM is installed. This is a normal part of the process as different modules in the vehicle communicate and verify security handshakes.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct operation of the brake lights and stability control systems.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. This Body Control Module comes fully programmed to your vehicle’s VIN before it is shipped. It is a plug-and-play solution that saves you a trip to the dealership and their associated programming fees.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your part without it.
Where is the BCM located on a 2008-2012 Express 3500?
On most Express and Savana vans of this generation, the BCM is located behind the dashboard, typically in the center dash area. Access may require removing some dash panels.
What happens if I don’t perform the post-installation procedures?
If required for your vehicle, failing to perform procedures like the airbag sync can result in a persistent airbag warning light on your dash. A brake pedal position relearn ensures your brake lights and traction control function as intended. These are critical safety functions.
Is there a core charge for this part?
No, there is no core charge. You can keep your old, original module without needing to send it back to us.
