Restore Your Van’s Electrical Systems with a Plug-and-Play BCM
Are you experiencing frustrating electrical issues in your 2004-2007 Chevrolet Express or GMC Savana Van? Flickering lights, unresponsive power windows, a malfunctioning security system, or erratic HVAC controls are common 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 problems. This OEM-quality replacement BCM, part number 15136877, is the definitive solution to restore your van’s functionality and reliability.
Is Your Express Van Showing Signs of BCM Failure?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following symptoms, it’s highly likely your Body Control Module needs replacement:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ HVAC and climate control problems, such as a blower motor stuck on one speed or not working.
- ✔ An illuminated airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Vehicle security system issues, including false alarms or no-start conditions.
- ✔ Wipers that behave unpredictably or fail to operate.

Installation & Post-Install Notes
Installation is simple for the average DIY mechanic. The BCM on the 2004-2007 Express/Savana van is typically located in the center of the dash. Always disconnect the battery before swapping modules. In most cases, the vehicle will start and function correctly immediately. However, please note the following potential post-installation procedures:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does a Body Control Module do on my Express 3500 Van?
The BCM acts as the brain for your van’s body electronics. It controls non-engine related functions like your lights, power windows and locks, wipers, security system, and HVAC fan speeds.
Is this BCM ready to install out of the box?
Yes! We pre-program the module to your vehicle’s VIN before shipping. This ensures it communicates correctly with your van’s other systems for a true plug-and-play installation, with no dealership visit required.

On the Express and Savana vans with the commercial tradesman package, the BCM is typically found in the center dash area.
What if my airbag light turns on after I install the new module?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.

No. This part is sold with no core charge, so you can keep your old module without any extra fees or hassle.
