Restore Full Electronic Function to Your GM Vehicle
Are you battling bizarre electrical gremlins in your 2008-2012 Express Van or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or even a no-start condition often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. This replacement Body Control Module, part number 20864767, is the definitive solution to restore your vehicle’s reliability and functionality.
From the Diagnostic Bay
We had a 2011 Savana work van come in that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and sometimes the power door locks wouldn’t respond. He’d already replaced the battery and checked fuses with no luck. After connecting our scanner, we saw multiple communication errors pointing towards the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The van was back in service the same afternoon with all electrical systems operating perfectly. It’s a common failure, and having a VIN-programmed module ready to install is a game-changer for a quick and effective repair.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Instrument cluster gauges behaving erratically or displaying warning lights.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ Communication errors with other vehicle modules when scanned.
Why Choose Our Pre-Programmed 2008-2012 Express 1500 BCM?

The critical advantage is our complimentary programming service. Simply provide us with your vehicle’s VIN during checkout, and we will flash the module with the latest GM software specific to your vehicle’s configuration. This ensures that when the part arrives, it’s ready for installation, saving you time, money, and a trip to the repair shop.
Installation and Post-Install Procedures
While this 2008-2012 Express 1500 BCM is designed for a straightforward installation, some vehicles may require minor post-installation steps known as ‘relearn’ procedures. These are simple electronic handshakes between the new BCM and other vehicle systems. Common procedures include:
- Airbag System Sync: If your 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: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn may be necessary.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s body and cabin electronics. It controls functions like power windows, locks, lights, wipers, the security system, and the instrument cluster.
Do I need to get this module programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN number at checkout, and it will arrive ready to be installed with the latest software for your specific vehicle.
Where is the BCM located on my 2008-2012 Express Van?
On the Express and Savana vans, the BCM is typically located in the center of the dashboard, often accessible by removing dash panels. On other compatible models like the Impala or Acadia, it’s usually on the driver’s side, under or to the left of the steering column.
Is this a plug-and-play installation?
For the most part, yes. You disconnect the old module and connect the new one. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems, which may require a professional scan tool.
My original part number isn’t 20864767, but it’s on your list. Will this work?
Yes. This BCM is a direct replacement for all the part numbers listed in the description. We will program it to function identically to the original module that came in your vehicle.
