Are you battling frustrating electrical issues in your GMC Savana or other compatible GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts on its own, or an unexplainable battery drain are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s proper function and reliability.
This is not just a part; it’s a complete, ready-to-install solution. We program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures that the BCM communicates correctly with your van’s other electronic systems, saving you a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, loading it with the latest software updates from GM for optimal performance.
From the Diagnostic Bay
We had a 2011 Savana 2500 work van come in that was driving the owner crazy. The dome lights would randomly turn on overnight, killing the battery. The power locks worked only when they wanted to. After checking the battery, alternator, and wiring for shorts, we traced the issue to the BCM. It was sending phantom signals to various accessories. Installing a VIN-programmed Savana 1500 Body Control Module like this one solved every single issue instantly. The driver was back on the road the same day without the persistent worry of a dead battery in the morning.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Security system faults or the alarm going off randomly.
- ✔ Intermittent warning lights on the instrument cluster, such as the airbag light.
- ✔ A battery that repeatedly dies overnight due to parasitic drain.
- ✔ Wipers or radio behaving unpredictably.
- ✔ Communication errors with diagnostic scan tools.

Post-Installation Procedures
While our VIN programming makes installation much simpler, some vehicles may require minor additional steps. These can typically be performed by a qualified mechanic with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
