Are you battling persistent and unpredictable electrical issues in your GMC Savana or Chevrolet Express van? A faulty Body Control Module (BCM) is often the culprit behind problems like malfunctioning lights, erratic power windows, a dead HVAC system, or even a no-start condition. This genuine GM BCM, part number 15194170, is the definitive solution, arriving expertly programmed to your vehicle’s specific VIN. This eliminates the need for costly dealership programming, allowing for a straightforward, plug-and-play installation that restores your van’s full electrical functionality.
We had a 2006 Savana 2500 work van come into the shop with a classic ‘ghost in the machine’ problem. The driver reported the dome lights would stay on intermittently, draining the battery overnight. On top of that, the driver’s side power lock was completely dead. We checked grounds and wiring harnesses, but everything looked solid. After connecting our diagnostic tool, we saw multiple communication error codes pointing to the BCM. We installed a VIN-programmed module just like this one, and within 10 minutes, the lights, locks, and communication network were all operating perfectly. It saved the owner from losing another day of work to a dead battery.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional HVAC controls and blower motor.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ Illuminated airbag warning light, often with DTC B1001.
- ✔ Vehicle security system acting up, causing false alarms or preventing the engine from starting.
- ✔ A variety of seemingly unrelated electrical glitches that come and go.
Why Choose Our 2004-2007 Savana Body Control Module?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The critical step of VIN programming is done for you before the module ships. This ensures that the BCM communicates flawlessly with your van’s other electronic systems, such as the Engine Control Module (ECM) and Powertrain Control Module (PCM), right out of the box. By matching the module to your van’s factory settings and options, we ensure optimal performance and reliability without any additional setup required on your end.
Installation is simple: The BCM on these vans is typically located in the center dash area. Disconnect the vehicle’s battery, carefully unplug the electrical connectors from the old module, remove it, and install the new one in its place. Reconnect the connectors and the battery. In most cases, the vehicle will start and function correctly immediately. However, for some vehicles, post-installation procedures may be necessary.
Post-Installation Notes:
- Airbag System: If the airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
- Brake System: A brake pedal position sensor relearn might be required on certain models to ensure correct brake light and traction control operation.

Frequently Asked Questions
What does a Body Control Module do on a GMC Savana?
The BCM acts as the central computer for your van’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this BCM truly plug-and-play?
Yes, because we program it to your vehicle’s VIN before shipping, it is ready for installation without needing a trip to the dealership for additional programming. This saves you time and money.
Where is the BCM located on a 2004-2007 Savana Van?
On the Savana and Express vans, the Body Control Module is typically found behind the center dash panel, often near the radio or climate controls.
Do I need to return my old BCM?
No. This part is sold with no core charge, so you are not required to send your original module back to us.
What if my airbag light is on after installation?
If the airbag light appears, it means the new BCM needs to be synchronized with the airbag system’s SDM. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
