Restore Full Electrical Function to Your Van
Are you battling strange and frustrating electrical gremlins in your 2008-2012 GMC Savana or Chevrolet Express van? Issues like flickering lights, malfunctioning power windows and locks, or a persistent security system warning are classic signs of 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 confusing problems. This direct-fit replacement Body Control Module is the definitive solution to restore your van’s reliability and functionality.
From the Diagnostic Bay
We had a 2011 Savana 1500 work van come into the shop that was driving the owner crazy. The interior lights would stay on, the radio would randomly shut off, and sometimes the power door locks wouldn’t respond to the key fob. He had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes with various systems, all pointing back to one culprit. A faulty BCM was intermittently losing its mind. Replacing it with a pre-programmed unit like this one had the van’s electronics working perfectly in under an hour, getting a frustrated contractor back on the road to his next job.
Symptoms of a Failing 2008-2012 Savana BCM
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, a faulty Body Control Module is the likely cause:
- ✔ Erratic or non-functional power windows, mirrors, or door locks.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ The security system light is illuminated, or the “Service Theft System” message appears on the dash.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Key fob fails to lock or unlock the doors.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Instrument panel gauges behaving erratically or not working.
The Plug-and-Play Solution
Don’t waste time and money with a trip to the dealership. We simplify the repair process by programming this module specifically for your vehicle before it ships.

This ensures a seamless installation process, getting your van back to work without the need for expensive dealer-only programming tools.
Installation & Post-Install Syncing
Physically replacing the BCM is generally straightforward. However, after installation, certain systems may need to be synchronized with the new module. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure is required. This must be done with a professional-grade diagnostic tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN at checkout, and the module will arrive ready for installation. This saves you a costly trip to the dealership.
Where is the BCM located on my 2008-2012 Savana van?
On most GMC Savana and Chevrolet Express vans from this era, the Body Control Module is located behind the dashboard, typically in the center dash area. You may need to remove some dash panels to access it.
What is a core charge? Do I need to send my old part back?
A core charge is a deposit that is refunded when you return your old part. We do not have a core charge on this BCM, so you can keep your original module without any extra fees or hassle.
What if my airbag light is on after I install the new BCM?
This is a known possibility. The new BCM needs to be electronically introduced to the airbag system (SDM). This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure, which will sync the systems and turn off the light.
Will this BCM fix all of my van’s electrical problems?
This module will correct any issues directly caused by a failing BCM. While the symptoms listed are strong indicators, it is always best to have a proper diagnosis performed to confirm the BCM is the root cause before ordering.
