Restore Full Electronic Functionality to Your GM Truck or Van
Are you battling bizarre electrical issues in your 2003-2007 GM vehicle? Erratic lights, malfunctioning power windows, or a security system that has a mind of its own are common 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 cascade of frustrating and difficult-to-diagnose problems. This direct-fit, VIN-programmed BCM is the definitive solution to get your truck or van operating reliably again.
We had a 2005 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would flicker, the radio would cut out, and the power locks would randomly cycle while driving. He had already replaced the battery and checked all the grounds. After hooking up our scan tool, we saw multiple communication loss codes with various modules. The culprit? A failing BCM. Instead of a complex wiring chase, a simple swap with a pre-programmed module like this one resolved all the issues at once. It’s amazing how one component can cause so many different symptoms.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (flickering, staying on, or not turning on).
- ✔ Security system faults or the vehicle not starting due to a security issue.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication errors with other vehicle modules (U-codes).

Important Post-Installation Information
While this module is programmed for a straightforward installation, some vehicles may require additional steps to sync with other systems. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated 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 certain models, a brake pedal position sensor relearn may be necessary to ensure correct operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
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, security system, wipers, and more.
Is this BCM difficult to install?
Installation is generally straightforward. In most trucks, it’s located under the steering column, and in vans, it’s in the center dash. Since we program it to your VIN, the most complex part of the job is already done for you. Basic mechanical skills are all that’s typically required.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module.
