Are you battling persistent and frustrating electrical issues in your work van? A faulty Body Control Module (BCM) is often the culprit behind problems like malfunctioning lights, unresponsive power locks and windows, erratic HVAC behavior, and even no-start conditions. This replacement Body Control Module, part number 15136225, is the definitive solution for your 2004-2007 GMC Savana 3500 Van, arriving pre-programmed to your vehicle’s VIN for a straightforward, plug-and-play installation.
We had a contractor bring in his ’06 Savana 3500. The dome lights wouldn’t turn off, the power locks worked intermittently, and the radio would randomly shut down—a nightmare for someone who practically lives in their van. He suspected a wiring issue, but a quick scan showed multiple communication DTCs pointing to the BCM. After installing a VIN-programmed module, every single issue was resolved in under 10 minutes. He was back on the road to his next job, relieved that the fix was so simple and didn’t require a costly trip to the dealership.
Common Symptoms of a Failing Savana BCM
- ✔ Unresponsive or erratic power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t work at all.
- ✔ HVAC system problems, such as a blower motor that won’t turn on or can’t be controlled.
- ✔ An active airbag warning light, often accompanied by diagnostic trouble code B1001.
- ✔ Vehicle security system malfunctions, leading to a no-start or crank-no-start situation.
- ✔ False warnings on the instrument cluster or non-functional gauges.

Installation & Post-Install Notes:
Physical installation is simple. The BCM is typically located in the center dash area on Savana models. Always disconnect the battery before swapping the modules. While the unit is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light is illuminated after install. Similarly, a brake pedal position sensor relearn may be needed. There is no core charge, so you can keep your old part without any hassle.

Frequently Asked Questions
What does a Body Control Module do on a Savana Van?
The BCM acts as the central computer for your van’s body electronics. It controls non-engine related functions like power windows, locks, interior/exterior lights, wipers, the security system, and the HVAC blower motor.
Is this BCM ready to install out of the box?
Yes, this module comes pre-programmed to your vehicle’s VIN for plug-and-play installation. In some cases, a post-installation relearn procedure for the airbag or brake pedal position sensor may be required using a professional scan tool.
Where is the BCM located on a 2004-2007 Savana Van?
On the 2004-2007 Savana and Express vans, the Body Control Module is typically found in the center of the dashboard, accessible from below.
Will this fix my airbag light with a B1001 code?
If the BCM is the source of the fault, yes. However, after installation, you may need a technician with a capable scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new module with the airbag system and clear the light.
Do I need to send my old part back?
No. We do not require a core return for this part, so there is no core charge. You can keep your original module.
