Restore Peak Electrical Performance in Your GM Vehicle
Is your Chevy Express van or other GM vehicle plagued by mysterious electrical issues? Flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. This replacement Body Control Module, part number 15276271, is the definitive solution to get your vehicle’s features working reliably again.
From the Diagnostic Bay
We once had a 2010 Savana 2500 in the shop with a list of complaints as long as your arm: the dome light wouldn’t turn off, the driver’s side power lock was intermittent, and the radio would randomly shut off. The customer was convinced he needed a new BCM. Before swapping the module, we did a full systems check and found a corroded ground wire under the driver’s seat. A simple wire cleaning fixed every single issue. While a faulty BCM was a likely culprit, this case was a powerful reminder: always check your main power and ground connections before replacing a major electronic component. It can save you time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Malfunctioning security system, including random alarm activation or key fob issues.
- ✔ Inoperative windshield wipers or washers.
- ✔ Incorrect readings on the instrument cluster gauges.
- ✔ HVAC (heating and air conditioning) control problems.
- ✔ Communication errors with other vehicle modules, triggering various warning lights.
The Direct-Fit Solution: A VIN-Programmed Express 2500 Body Control Module
Don’t settle for a generic, off-the-shelf part that requires expensive dealership programming. We take the hassle and guesswork out of the repair. When you purchase this Express 2500 Body Control Module, you’re getting a component that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This crucial step ensures that the BCM communicates flawlessly with your vehicle’s existing systems, recognizes all factory options, and functions exactly as intended from the moment you install it. We load the latest, most stable software updates from GM, often correcting factory bugs and improving performance beyond the original part.
Simple Process, Professional Results
- Place Your Order: Add this BCM to your cart and complete the checkout process.
- Provide Your VIN: Reply to your order confirmation email with your vehicle’s 17-digit VIN.
- We Program & Ship: Our technicians will program the module with the latest GM software matched to your VIN and ship it directly to you.
Post-Installation Procedures
While our programming makes installation as straightforward as possible, some GM vehicles may require one or two simple relearn procedures after the new BCM is installed. These are standard industry procedures.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system and requires a professional-grade scan tool. This is only needed if the light appears.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration may be needed to ensure proper operation of the brake lights and traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do you need my VIN number?
Your vehicle’s 17-digit VIN is like its fingerprint. It contains crucial information about the specific options and systems installed at the factory. We use the VIN to load the exact software and calibration files from GM, ensuring the replacement BCM works perfectly with your vehicle’s features, such as its specific lighting, security system, and power accessories.
Is this a difficult part to install?
The physical installation is typically straightforward. The BCM is usually located under the dashboard on the driver’s side or in the center dash area. It involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. However, some vehicles may require post-installation relearn procedures as noted above, which may require a professional scan tool. We always recommend consulting a service manual for your specific vehicle.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module, which can be helpful for reference or if you ever need to revert to the original hardware for any reason.
Will this fix my specific electrical problem?
This Express 2500 Body Control Module is the solution for a wide range of electrical issues caused by a faulty BCM. If you are experiencing several of the symptoms listed above, it is highly likely that the BCM is the culprit. However, we always recommend proper diagnostics to rule out other potential causes like bad wiring, faulty grounds, or failing switches.
What if the airbag light comes on after I install it?
This is a known possibility on some GM models. It does not mean the BCM is defective. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure using a compatible high-end scan tool. A qualified repair shop can perform this sync for you.
