Are you battling frustrating electrical problems in your GM truck or van? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This replacement BCM, part number 15136224, is the definitive solution to restore full functionality and reliability to your vehicle.
We take the guesswork and hassle out of the repair process. Unlike a standard replacement, each module is professionally programmed with the latest GM software updates specifically to your vehicle’s VIN before it ships. This means you get a part that is ready for installation, saving you a costly trip to the dealership for programming. Simply provide us with your VIN upon purchase, and we’ll handle the rest.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows and door locks
- ✔ Interior or exterior lights that flicker, stay on, or won’t turn on at all
- ✔ The security system or alarm sounding randomly
- ✔ Inconsistent or non-working windshield wipers
- ✔ Warning lights on the dashboard, such as the airbag or brake light
- ✔ Radio or infotainment system malfunctions
- ✔ Problems with the keyless entry system
Plug-and-Play Solution for your 2003-2007 Express 2500 BCM
This BCM is a direct-fit replacement for a wide range of GM trucks and vans, including the Chevrolet Express, GMC Savana, Chevrolet Silverado, and GMC Sierra. By programming the module to your VIN, we ensure it communicates correctly with the other electronic systems in your vehicle right out of the box. While the core functions will be restored upon installation, some vehicles may require simple, on-vehicle relearn procedures for specific systems.
Post-Installation Procedures
Please be aware of the following potential procedures after installing the new BCM:
- 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’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship your order.
Is this part truly ‘plug-and-play’?
Because we program the BCM to your VIN, it is as close to plug-and-play as possible and will restore the main functions. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake sensor, which may require a capable scan tool.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system. A technician with a professional-grade diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this BCM fit a Crew Cab model?
Please check the detailed fitment list carefully. For many of the pickup truck models listed, this BCM is specified for models ‘exc. Crew Cab’ (excluding Crew Cab). It is crucial to match your vehicle’s options to the fitment data provided.
