Restore Full Electrical Function to Your GM Vehicle
Are you battling bizarre electrical problems in your Chevy Express, GMC Savana, or other GM vehicle? A failing Body Control Module (BCM) is often the culprit behind these frustrating issues. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and locks to your interior lights and security system. When it fails, it can cause a cascade of seemingly unrelated problems, making your vehicle unreliable and difficult to use.
This replacement Body Control Module is the definitive solution. It arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest official GM software updates, ensuring optimal performance and compatibility right out of the box. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Is Your BCM Failing? Common Symptoms
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, dome lights) staying on, flickering, or not working.
- ✔ The security system acting up, causing alarm issues or a “Service Theft System” message.
- ✔ Instrument panel gauges behaving erratically or providing incorrect readings.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ HVAC (heater and A/C) controls or blower fan not responding correctly.
- ✔ Horn honking unexpectedly or not working when pressed.

Installation and Post-Install Considerations
Physical installation is typically a simple plug-and-play process requiring basic hand tools. However, after the new BCM is installed, some vehicles may require additional electronic ‘relearn’ or ‘setup’ procedures to sync related systems. The most common are:
- Airbag System Sync: If your airbag warning light is on 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: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
How does the VIN programming work?
After you complete your purchase, you will need to provide us with your 17-digit VIN. Our technicians use this number to load the correct GM software and vehicle-specific settings onto the BCM before it is shipped to you.
Do I need to send my old BCM back?
No. This part has no core charge. You can keep your original module, which can be helpful for reference or as a backup.
Will this fix my exact problem?
This module will correct any issues directly caused by a faulty BCM. While the symptoms listed are common indicators of BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the source of the problem before ordering.
Is this part difficult to install?
The physical replacement is generally straightforward for someone with basic mechanical skills. The main consideration is the potential need for electronic relearn procedures after installation, which may require a bi-directional scan tool.
Is this a new part?
This is a quality-tested, guaranteed functional component. It is programmed with the newest software available from GM to ensure it performs reliably for years to come.
