Restore Full Functionality to Your GM Vehicle’s Electronics
Are you battling bizarre electrical gremlins in your 2008-2012 Express 1500 Van or other compatible GM model? Issues like flickering interior lights, malfunctioning power windows and locks, an unresponsive security system, or erratic dashboard warnings often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module is your direct, reliable solution, pre-programmed to your vehicle’s specific VIN for a straightforward installation.
From the Diagnostic Bay
We had a 2011 Express 2500 work van come into the shop that was driving the owner crazy. The dome lights would stay on, the power door locks worked only when they wanted to, and the radio would randomly shut off. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication loss codes with the BCM. Instead of spending hours tracing wires for a potential short, we installed a VIN-programmed BCM. All the strange electrical issues vanished instantly. It’s a common failure point that can mimic a dozen other problems, but a quality replacement is often the definitive fix.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t turn on at all.
- ✔ The security or anti-theft light stays illuminated, preventing the vehicle from starting.
- ✔ Erratic or non-functional windshield wipers and washers.
- ✔ Horn activating unexpectedly or not working when pressed.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’).
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.

Installation and Post-Install Procedures
On most Express and Savana vans, the BCM is located in the center dash area. While installation is often plug-and-play, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on 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: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Disclaimer: 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 program this BCM?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready for installation, saving you a trip to the dealership.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot ship your part until we receive this information.
Where is the BCM located on my 2008-2012 Express 1500 Van?
The Body Control Module (BCM) on the Express 1500 Van is typically located behind the center part of the dashboard.
What if the airbag light comes on after I install it?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
