Restore Full Electrical Control to Your GM Vehicle
Are you dealing with frustrating electrical issues in your 2004-2007 Chevrolet Express 2500 Van? Flickering lights, unresponsive power windows, or a malfunctioning security system are common indicators of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of seemingly unrelated problems. This OEM-quality replacement BCM, part number 15137395, is the definitive solution to restore your vehicle’s functionality and peace of mind.
Expert Pro Tip: Before beginning the installation, always disconnect the negative terminal of your vehicle’s battery. This prevents the risk of electrical shorts and helps the vehicle’s systems reset and properly recognize the new module upon reconnection.
Is Your BCM Failing? Common Symptoms to Watch For
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong sign that your module needs replacement:
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, door locks, or mirrors that operate intermittently or not at all.
- ✔ HVAC and climate control problems, including an unresponsive blower motor.
- ✔ An active airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Vehicle security system issues, including no-start conditions where the engine won’t crank.
- ✔ Malfunctioning windshield wipers or washers.

Post-Installation Information
While this module is designed for plug-and-play installation, some vehicles may require a simple relearn procedure. If the airbag light remains on after installation, a technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. Always consult a service manual or a qualified mechanic if you are unsure about these steps.
Frequently Asked Questions

The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows, door locks, climate control (HVAC), security system, and wipers.

No. We pre-program the module to your vehicle’s VIN before it ships. It arrives ready to install, saving you time and money on dealership programming fees.
Where is the BCM located on a 2004-2007 Express Van?
On the Chevy Express and GMC Savana vans from this era, the BCM is typically found in the center of the dashboard, behind the lower trim panels.
Do I have to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any extra fees or hassle.
