Are you battling frustrating and unpredictable electrical issues in your GMC Savana or Express van? A faulty Body Control Module (BCM) is often the culprit behind problems that can disrupt your workday and compromise your vehicle’s security and convenience. This direct-fit BCM, part number 15948439, is the reliable solution to restore your van’s electronic systems to perfect working order.
The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your interior and exterior lights to power windows, door locks, and the security system. When it begins to fail, you can experience a wide range of bizarre symptoms that may seem unrelated. This replacement module is delivered to you pre-programmed with the latest GM software updates, specifically matched to your vehicle’s VIN. This critical step ensures a seamless installation process, saving you from expensive programming fees and a trip to the dealership.
Is Your Savana Van Experiencing These BCM Issues?
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system engaging randomly or not working at all.
- ✔ Warning lights on the dashboard, such as the airbag or brake light.
- ✔ Intermittent radio or climate control problems.
- ✔ A ‘no-start’ condition where the starter won’t engage.
- ✔ Rapid battery drain when the vehicle is off.

Getting your van back to full operational status is our priority. By providing us with your VIN upon purchase, we handle the complex programming for you.

Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to sync all systems perfectly:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do on a Savana van?
The BCM is the computer that controls most of the non-engine related electronic functions in your van, including power windows, locks, interior and exterior lighting, security system, and wipers.
Is this BCM plug-and-play?
Because we program it to your VIN before shipping, it is as close to plug-and-play as possible. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which requires a diagnostic tool.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the module before shipping it to you.
Will this fix my specific electrical problem?
This module will correct issues caused by a failed BCM. The symptoms listed are the most common indicators of BCM failure. However, we always recommend a proper diagnosis by a qualified technician to rule out other potential causes like wiring or switch failures.
My original part number is on your list, but it’s not 15948439. Is this correct?
Yes. Part number 15948439 is a superseded part that replaces all the older numbers listed. If your part number is on our cross-reference list, this module is the correct, updated replacement for your vehicle.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module.
