Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, power windows with a mind of their own, or a security system that randomly acts up, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable issues. This isn’t just an annoyance; it can affect the safety and reliability of your vehicle. This replacement Body Control Module is the definitive solution to restore full functionality and peace of mind to your driving experience.
We take the guesswork and hassle out of the repair. Unlike a generic module from a parts store or salvage yard, this BCM is professionally programmed specifically for your vehicle using your VIN. We flash it with the latest, most stable software updates directly from GM, ensuring optimal performance and compatibility. This means no expensive trips to the dealership for programming. Simply provide your VIN after purchase, and we’ll ship a module that’s ready for installation.
From the Diagnostic Bay
We had a 2000 Silverado 1500 come into the shop with a classic case of BCM failure. The owner was at his wit’s end. The dome light would stay on for hours, draining the battery, and the power door locks would cycle on and off while driving down the road. He had already replaced the battery and checked all the fuses. After a quick scan, we confirmed communication errors with the BCM. We installed one of our pre-programmed modules, and within 20 minutes, every single issue was resolved. The relief on the customer’s face was a testament to how disruptive a faulty BCM can be, and how simple the right solution is.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Erratic instrument cluster behavior or warning lights (like the airbag light).
- ✔ Radio or climate control malfunctions.
- ✔ No-start conditions where the starter doesn’t engage due to security system confusion.

Installation and Post-Install Procedures
The BCM is typically located under the driver’s side of the dashboard. While the physical installation is straightforward for a DIYer with basic tools, some vehicles may require simple electronic relearn procedures after the new module is connected. These are not complex programming steps but rather synchronization tasks that can sometimes be necessary.
- 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’ function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper function of the brake lights and traction control system.
Please note: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls your vehicle’s non-engine related electronic functions. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more.
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready for installation.
Where is the BCM located on my 2000 Tahoe or Silverado?
On most of these GM trucks and SUVs, the BCM is located on the driver’s side, up under the dashboard, often near the steering column or parking brake pedal assembly.
What if my airbag light comes on after I install the new BCM?
This indicates the new BCM needs to be electronically synced with the airbag’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
Will this fix my specific electrical problem?
This module is the solution for failures within the BCM itself, which cause the common symptoms listed above. While it resolves the vast majority of these issues, it’s always best to have a proper diagnosis to confirm the BCM is the source of the problem before ordering.
