Restore Your Van’s Electrical Systems with a Plug-and-Play Solution
Is your 2008-2012 Chevy Express van experiencing bizarre electrical problems? The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and door locks to the interior lights and security system. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues.

We take the guesswork out of the repair. Simply provide your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your Express 1500. This ensures a seamless installation process, eliminating the need for an expensive trip to the dealership for programming. This is a direct-fit replacement for part number 15872421 and many other interchangeable part numbers.
From the Diagnostic Bay
We had a customer with a 2011 Express work van whose driver-side power window and lock would only work intermittently. He had already replaced the switch and the window motor, but the problem persisted. After a quick scan, we saw communication fault codes pointing to the BCM. Instead of continuing to replace parts, we installed a VIN-programmed BCM. The new module instantly resolved the window, lock, and even a flickering dome light issue he hadn’t mentioned. It’s a classic case of the BCM being the true source of multiple electrical gremlins.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The vehicle’s security system malfunctioning or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ The radio or climate control system behaving unpredictably.

Post-Installation Information
After installing your new BCM, some vehicles may require additional relearn procedures. These are simple steps that can often be completed with a capable bi-directional scan tool. The most common are:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Always consult your vehicle’s factory service manual or a qualified technician for specific instructions.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
Is this part difficult to install?
The physical installation is typically straightforward for someone with moderate DIY mechanical skill. The BCM is usually located in the center dash area on Express vans. The key benefit of our service is that the complex programming is already done for you.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after I install this?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Does this BCM fit other vehicles besides the Express van?
Yes, this BCM is compatible with a wide range of GM vehicles from the same era, including the GMC Savana, Chevy Tahoe, GMC Acadia, Chevy Impala, and more. Please check the detailed fitment list on this page to confirm compatibility with your specific model.
