Restore Full Electrical Function to Your GM Van or Truck
Are you battling strange electrical gremlins in your 2004-2007 GMC Savana or other compatible GM vehicle? Intermittent wipers, flickering lights, malfunctioning power locks, or a dead HVAC system are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This genuine OEM-quality module, part number 10383536, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play installation.
From the Diagnostic Bay
We had a 2006 Savana 2500 work van come in that was driving the owner crazy. The dome lights wouldn’t turn off, the power locks worked only when they wanted to, and the radio would randomly shut off. The owner had already replaced the battery and checked all the fuses. After connecting our scanner, we saw multiple communication loss codes with the BCM. Instead of a complex wiring repair, the fix was simple: this pre-programmed BCM. We swapped it out in under 10 minutes, and every single electrical issue was resolved instantly. It saved the owner hours of diagnostic labor and got his van back on the road earning money.
Signs Your Body Control Module is Failing
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or failing to illuminate.
- ✔ HVAC and climate control systems being unresponsive or blowing air incorrectly.
- ✔ The vehicle’s security system malfunctioning, causing no-start conditions or false alarms.
- ✔ Airbag warning light illumination, often accompanied by DTC B1001.
- ✔ Wipers that won’t turn on, off, or operate at the correct speed.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs) stored in the system.

Post-Installation Procedures
While this module is designed for easy installation, some vehicles may require additional steps to ensure all systems are synchronized:
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming loads your vehicle’s specific software and settings onto the BCM. This is crucial for ensuring all your van’s features, like power windows, security system, and HVAC, work correctly. Our service saves you a mandatory trip to the dealership.
Is this a difficult part to install myself?
For most DIYers, the installation is simple. In the Savana/Express vans, the BCM is typically located in the center dash area. It involves disconnecting the battery, removing a few trim pieces, and swapping the electrical connectors. The entire process often takes less than 15 minutes.
Will this BCM fix my airbag light with code B1001?
Yes, a faulty BCM is a very common cause of the B1001 trouble code. Replacing the module often resolves this issue. However, after installation, you may need a professional scan tool to perform the ‘Setup SDM Primary Key’ procedure to sync the new BCM with the airbag system and clear the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any extra fees or hassle.
What vehicles does this part fit besides the Savana van?
This BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Chevrolet Silverado, Tahoe, Suburban, Avalanche, GMC Sierra, Yukon, Cadillac Escalade, and Hummer H2. Please check the fitment list to confirm for your specific model.
