Are you dealing with frustrating electrical gremlins in your GM truck or van? Issues like erratic power windows, door locks that have a mind of their own, a security light that won’t turn off, or interior lights that flicker can often be traced back to a single component: the Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module is the definitive solution to restore full functionality and reliability to your vehicle’s essential features.
We take the guesswork and hassle out of the repair. Unlike a standard replacement, this BCM arrives at your door pre-programmed with the latest GM software, specifically flashed to your vehicle’s VIN. This means you can avoid a costly trip to the dealership for programming. Simply provide us with your VIN after purchase, and we’ll handle the rest, ensuring a seamless and straightforward installation process.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ The security or anti-theft light stays illuminated on the dashboard.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Remote keyless entry failing to lock or unlock the doors.
- ✔ Communication errors with diagnostic scan tools.
Installation and Post-Install Steps for your GM Truck Van BCM
Physically replacing the BCM is typically a simple process. On most compatible trucks (Silverado, Sierra), it’s located under the driver’s side of the dashboard near the steering column. On vans (Express, Savana), it’s often found behind the center dash panel. Once the new, pre-programmed module is installed, your vehicle should start and run. However, depending on your specific model and options, a couple of additional steps, known as relearn procedures, might be necessary:
- Airbag System Sync: If the 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: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before shipping it to you. This saves you time and the expense of dealer programming.
Where is the BCM located on my 2005 Silverado?
On most 2003-2007 Silverado and Sierra pickups, the BCM is located under the driver’s side dashboard, near the steering column. On Express and Savana vans, it is typically behind the center dash area.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is this a plug-and-play part?
Yes, for the most part. Because we program it to your VIN, the vehicle will start and run upon installation. However, as noted, some vehicles may require minor relearn procedures for the airbag or brake pedal position sensor for full system functionality.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
