Is your GMC Savana 2500 van plagued by perplexing electrical issues? If you’re dealing with flickering lights, malfunctioning power windows or locks, or a security system that has a mind of its own, a failing Body Control Module (BCM) is the likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating problems. This replacement Body Control Module, part number 15299986, is the definitive solution to restore your van’s functionality and reliability.

Before diagnosing a faulty BCM, always verify the health of your vehicle’s battery and check for clean, tight main ground connections. A weak battery or poor ground can mimic BCM failure symptoms by causing low voltage conditions that confuse the vehicle’s electronic systems. A simple check can save you time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Intermittent issues with the radio or instrument cluster.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ A no-start condition where the engine cranks but won’t fire up due to security system intervention.
- ✔ Diagnostic trouble codes related to communication or specific body functions.

You get a part that is ready for installation right out of the box, saving you the time, expense, and hassle of a trip to the dealership for programming.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require additional on-vehicle relearn procedures after installation. These are standard steps for many modern vehicle repairs.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn may be necessary.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
