Are you battling frustrating electrical issues in your 2004-2007 Chevy Express 3500? Flickering lights, unresponsive power windows, a malfunctioning HVAC system, or a security light that prevents your van from starting 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 cascade of confusing and disruptive problems. This OEM-quality replacement BCM, part number 15137394, is the definitive solution to restore your van’s reliability and functionality.
Is Your Express Van Showing Signs of BCM Failure?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, a failing module is the likely culprit:
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ HVAC blower motor not working or climate controls functioning intermittently.
- ✔ The security or anti-theft system light is on, causing a no-start condition.
- ✔ An active airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Strange electrical behavior, such as wipers turning on by themselves or incorrect gauge readings.
- ✔ Multiple communication DTCs related to body systems.

Installation and Post-Install Notes
Installation is straightforward. The BCM on the Express Van is typically located in the center of the dash. Always disconnect the vehicle’s battery before removing the old module to prevent electrical shorts and help reset related systems. In most cases, the installation is plug-and-play. However, depending on your vehicle’s specific configuration, a couple of post-installation procedures may be necessary:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
There is no core charge for this part, so you can keep your old module without the hassle of returning it.
Frequently Asked Questions
What does a Body Control Module do on a Chevy Express Van?
The BCM acts as the brain for your van’s body electronics. It controls non-engine related functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
