Are you experiencing frustrating electrical issues with your GMC Savana or Chevrolet Express van? Problems like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your van’s body electronics, and when it fails, it can cause a wide range of perplexing symptoms. This replacement module is the definitive solution to restore full functionality and reliability to your vehicle.
We make the repair process straightforward. This unit comes fully programmed with the latest GM software updates, specifically matched to your vehicle using your VIN. This means you can avoid a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the configuration before shipping it directly to you. This ensures a smoother installation process, getting your work van or passenger van back on the road with minimal downtime.
From the Diagnostic Bay
We had a 2011 Savana 2500 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 had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication errors pointing towards the BCM. Instead of a complicated diagnostic and programming session at the dealer, he ordered one of our pre-programmed modules. The installation was simple, and it immediately solved all the electrical gremlins. He was back on the job the next day, a testament to how a reliable Savana 1500 Body Control Module can eliminate headaches and prevent lost income.
Common Failure Symptoms:
- ✔ Erratic or non-working interior and exterior lights
- ✔ Power windows, door locks, or mirrors functioning intermittently or not at all
- ✔ Horn honking unexpectedly or not working when pressed
- ✔ Vehicle security system faults or false alarms
- ✔ Inaccurate gauge readings or warning lights on the dash
- ✔ Communication issues with other vehicle modules, leading to a no-start condition
- ✔ Problems with the heating and A/C blower motor controls
Installation and Post-Install Considerations
While this Savana 1500 Body Control Module is designed for a direct fit, some vehicles may require additional steps after installation to ensure all systems are synchronized. These are known as relearn procedures. Depending on your vehicle’s specific options, you may need a professional scan tool to perform an ‘Airbag System Sync’ if the airbag light appears, or a ‘Brake Pedal Position Relearn’ to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do on a Savana van?
The BCM acts as the brain for your van’s electronic accessories. It controls functions like the power windows, door locks, interior/exterior lighting, security system, horn, and wiper system. When it fails, these systems can behave erratically.
Is this BCM truly plug-and-play?
Because we program it to your vehicle’s VIN before shipping, it is as close to plug-and-play as possible. However, some vehicles may require additional relearn procedures for systems like the airbags or brake pedal position sensor, which may require a professional scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on your vehicle’s registration.
What happens if I don’t perform the post-installation procedures?
If a procedure like the Airbag System Sync is required and not performed, you may have a persistent airbag warning light on your dash. If the Brake Pedal Position Relearn is needed, your brake lights or traction control may not function correctly.
Will this fix my ‘Service Airbag’ light?
If the airbag light is caused by a faulty BCM, this part will resolve the root cause. However, after installation, you will still need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to sync the new BCM with the airbag system and clear the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
