Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Instrument cluster warning lights (like the airbag light) illuminating for no reason.

- ✔ Radio or climate control malfunctions.
- ✔ A parasitic battery drain that kills your battery overnight.
Installation and Post-Install Requirements
Installing a properly programmed 2003-2007 GM Body Control Module is crucial for restoring full functionality. While our VIN programming makes this a near plug-and-play part, some vehicles may require additional steps after the physical installation. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic body functions that are not related to the engine. This includes power windows, locks, lights, wipers, the security system, and more.
Do I need to have this BCM programmed?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will flash the module with the correct software for your specific vehicle.
Where is the BCM located on my truck or van?
Location varies by model. On most Silverado and Sierra pickups, the BCM is found under the steering column. On Express and Savana vans, it is typically located in the center of the dashboard.
What if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a high-level diagnostic 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 old module without needing to send it back.
