Is your GM truck or van acting possessed?
If you’re dealing with flickering lights, power windows and locks that have a mind of their own, or a security system that won’t cooperate, the problem is likely a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it malfunctions, it can cause a cascade of frustrating and seemingly unrelated electrical issues. Don’t let these problems sideline your truck. This is the reliable, straightforward solution you need.
From the Diagnostic Bay
We had a 2006 Silverado 2500 in the shop that was driving the owner crazy. The interior dome lights would stay on intermittently, draining the battery overnight. He’d already replaced the battery twice. After confirming all door jamb switches were working, we connected our diagnostic tool and found multiple communication fault codes originating from the BCM. We installed one of our pre-programmed modules, and the problem was solved instantly. The customer was thrilled to have his reliable work truck back without a costly trip to the dealership for diagnostics and programming.

This means no expensive dealer programming is required. It arrives at your door ready for installation, saving you time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Unexplained warning lights on the instrument cluster (like the airbag light).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication issues with diagnostic scan tools.
Simple Installation Process
This module is a direct replacement for your original unit. For most trucks, it’s located under the steering column; for vans, it’s typically in the center dash. Once installed, some vehicles may require simple post-installation procedures to ensure all systems communicate correctly.
Post-Installation Steps:
- 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 necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Is this BCM truly plug-and-play?
Yes, it’s designed to be as close to plug-and-play as possible. We pre-program it to your VIN, which handles the most critical step. However, as with any module replacement, some vehicles may require minor relearn procedures for systems like the airbags or brake sensor, which may require a professional scan tool.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
What happens if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A qualified mechanic with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fix my specific electrical problem?
If your issues match the common symptoms of a failing BCM (erratic lights, locks, windows, etc.) and you’ve ruled out simpler causes like fuses or relays, then this programmed 2003-2007 Silverado BCM is very likely the solution.
