Fix Your Van’s Electrical Headaches for Good
If you’re dealing with the frustrating and unpredictable electrical problems common in GM vans and trucks, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable workhorse into a source of daily frustration. This VIN-programmed Body Control Module, a direct replacement for part number 10367690, is the definitive solution for your 2004-2007 GMC Savana 3500 Van and a wide range of other GM vehicles. It restores full control over your vehicle’s essential electronic features, getting you back to work without a costly trip to the dealership.
Case Study: A Tricky Diagnosis
A local contractor brought in his ’05 Savana 3500. The complaint was a classic “ghost in the machine”: the dome lights would stay on, the power locks worked only when they wanted to, and the radio would sometimes cut out. He’d already replaced the battery and checked fuses. After connecting my scanner, I saw a handful of communication codes pointing to the BCM. These modules are notorious for internal circuit board failures causing these exact symptoms. We installed one of our pre-programmed BCMs, and in under 10 minutes, every single issue was resolved. He was back on the road to his next job, saving hundreds compared to the dealership’s quote.
Is Your GM Truck or Van Showing These Signs?
A faulty BCM can cause a cascade of issues that seem unrelated. If you’re experiencing any of the following, a failing module is the likely culprit:
- ✔ Inoperative or erratic power windows, door locks, or mirrors.
- ✔ HVAC blower motor not working or stuck on one speed.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The security light is on, and the vehicle won’t start (anti-theft system malfunction).
- ✔ An airbag warning light on the dash, often with a DTC like B1001 (Setup SDM Primary Key in BCM).
- ✔ Intermittent wiper operation or wipers that won’t turn off.
- ✔ Communication errors with other modules on the vehicle’s network.
Plug-and-Play Installation: Get Back on the Road Fast
One of the biggest benefits of this module is its simplicity. Because we program it to your vehicle’s VIN before shipping, the installation is a straightforward swap. No special tools are needed for the basic installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and to help reset the system.
- Locate the BCM: On a 2004-2007 Savana 3500 Van, the BCM is typically found in the center of the dash. On trucks like the Silverado or Sierra, it’s usually under the steering column to the left of the brake pedal.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Remove the old module and install the new one in its place.
- Reconnect and Test: Reconnect the electrical connectors to the new BCM, ensuring they click securely into place. Reconnect the battery terminal. Start the vehicle and test all functions (lights, locks, windows, wipers, HVAC) to confirm the repair.
- Post-Install Check: In some cases, an airbag light may remain on. This requires a professional scan tool to perform the ‘Setup SDM Primary Key’ procedure to sync the airbag system. This is a simple procedure for any competent repair shop.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and all its specific options into the module before we ship it. This ensures it communicates perfectly with your vehicle’s other computers (like the Engine and Transmission controllers) right out of the box, just like an OEM part from the factory.
Do I need to return my old BCM? Is there a core charge?
No. We believe in a hassle-free process. There is absolutely no core charge, and you are not required to send your old, faulty module back to us.
What if my airbag light is on after I install the new module?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A repair shop with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is this a difficult part for a DIYer to replace?
Not at all. For most people with basic hand tools and a little patience, this is a 5-15 minute job. The main challenge is simply accessing the module’s location under the dash. The physical swap is very simple.
Will this fix my no-start problem?
If your no-start condition is caused by the BCM’s control over the Passlock/Passkey anti-theft system, then yes, this will resolve it. The VIN programming ensures the security data matches your vehicle’s key.
