Restore Full Functionality to Your GM Truck or Van
Are you battling bizarre electrical problems in your 2003-2007 GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up are classic signs of 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 difficult-to-diagnose symptoms. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Symptoms of a Failing GM Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your BCM is the culprit:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ The vehicle failing to start, accompanied by a security light on the dash.
- ✔ Inaccurate gauge readings or gauges that stop working altogether.
- ✔ Unexplained battery drain that leaves you with a dead battery.
A True Plug-and-Play Solution
Don’t waste time and money at the dealership. We make the replacement process simple. When you purchase this module, you provide us with your vehicle’s VIN. Our technicians will then flash the BCM with the latest, most stable software direct from GM, ensuring it is perfectly matched to your vehicle’s specific options and configuration. It arrives at your door ready to install, with no additional programming required. This eliminates the need for expensive scan tools or a trip to a mechanic for programming.
Post-Installation Procedures
While this module is programmed for your VIN, some vehicle systems may require a simple relearn procedure after installation to sync properly. These can often be done with a capable diagnostic tool.
- Airbag System Sync: If your airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
Please note: 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 acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and interior accessories.
Do I need to program this module?
No! This is the biggest benefit of our service. We program the module to your vehicle’s specific VIN before we ship it. It arrives ready for installation, saving you a trip to the dealership.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
Is this part difficult to install?
The BCM is typically located under the steering column or in the center dash area. Installation involves disconnecting the battery, removing a few trim panels, and swapping the module. It’s a manageable job for a DIYer with basic tools, but we always recommend consulting a service manual.
What if the airbag light is on after I install it?
This can happen. It means the new BCM needs to be synced with the airbag module (SDM). A professional scan tool is required 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 original module.
