Restore Full Electrical Function to Your GM Vehicle
Are you battling bizarre electrical gremlins in your van or SUV? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or even a vehicle that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable issues. This replacement module is the definitive solution to restore your vehicle’s electronic stability and functionality.
From the Diagnostic Bay
We had a 2011 Express work van come into the shop that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and worst of all, it would intermittently fail to crank. The battery and starter checked out fine. After connecting our diagnostic tool, we saw multiple communication error codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and programming, the owner opted for one of our pre-programmed units. We installed it, performed the quick brake pedal position relearn, and the van’s electrical system was back to behaving perfectly. It’s a common story for these hard-working vehicles.
Is a Failing Express 1500 Body Control Module Causing Your Problems?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a replacement is likely the solution you need. This module is a direct-fit replacement, programmed specifically for your vehicle to ensure a straightforward installation.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Warning lights on the dashboard (like the airbag or security light).
- ✔ Inaccurate fuel gauge or other instrument cluster problems.
- ✔ HVAC (heating and air conditioning) controls not responding.
Plug-and-Play Solution with VIN-Specific Programming
Don’t waste time and money at the dealership. We take the hassle out of the repair process. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) after your purchase, and our technicians will program this module with the latest GM software updates specific to your van. This ensures that the module communicates perfectly with your vehicle’s other systems right out of the box, saving you from expensive programming fees.
Post-Installation Requirements
While this module is delivered ready for installation, some vehicles may require simple relearn procedures to sync all systems. These are standard procedures after a BCM replacement.
- Airbag System Sync: If your 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: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and the instrument cluster.
Is this part difficult to install?
Because we program the module to your VIN before shipping, the physical installation is typically straightforward. However, some vehicles may require additional key programming or relearn procedures (like for the airbag or brake pedal sensor) with a professional scan tool to complete the process.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module without it.
Do I need to return my old BCM?
No. This part is sold without a core charge, so you can keep your original module.
Will this fix my vehicle’s specific electrical problem?
This module will resolve any issue directly caused by a faulty BCM. Please review the list of common failure symptoms. If your vehicle’s issues match, this is very likely the solution. Proper diagnosis is always recommended.
What vehicles does this BCM fit?
This BCM fits a wide variety of GM vehicles, including the 2008-2012 Express/Savana vans, 2007-2012 Acadia, 2006-2012 Impala, and many others as detailed in the full fitment list. Please verify your part number to ensure compatibility.
