Is your Chevy Express or GMC Savana van plagued by bizarre electrical problems? If you’re dealing with flickering lights, malfunctioning power accessories, or a security system that has a mind of its own, the culprit is often a faulty Body Control Module (BCM). This central computer acts as the brain for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating issues. This replacement BCM is the definitive solution for your 2008-2012 Express 1500 Van and many other GM vehicles, arriving pre-programmed for a straightforward installation.
We recently serviced a 2011 GMC Savana 2500 that was driving its owner, a contractor, crazy. The interior dome lights would stay on, draining the battery overnight and making him late for jobs. His key fob stopped working, and the horn would randomly honk. After confirming power and grounds were good, we diagnosed a failing BCM. Installing a pre-programmed module like this one resolved all the issues in one go. It’s a common failure point, but thankfully, it’s a straightforward fix with the right part.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system preventing the vehicle from starting (anti-theft light on).
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Remote keyless entry (RKE) system failure.
- ✔ Intermittent issues with the radio or climate control system.

Post-Installation Procedures
While our programming handles the heavy lifting, some vehicles may require a simple relearn procedure after the new BCM is installed. These can often be performed with a capable diagnostic tool:
- Airbag System Sync: If the airbag warning light comes on after installation, the ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional diagnostic tool to sync the system and turn off the light. This is a security measure and is only required if the light appears.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary to ensure proper brake light function and traction control system performance.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine related electronic functions. This includes power windows, locks, lights, security system, wipers, and more.
Do I need to program this BCM?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready for installation.
Where is the BCM located on my Express or Savana van?
On most 2008-2012 Express and Savana vans, the BCM is located in the center dash area. Always consult a service manual for your specific model to confirm the exact location and replacement procedure.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
What if my airbag light comes on after installation?
This is a normal security precaution on some models. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system with the new BCM and turn off the light.
