Restore Full Electrical Function to Your GMC Savana Van
Is your 2004-2007 GMC Savana 3500 plagued by bizarre electrical issues? Flickering lights, unresponsive power windows, a malfunctioning HVAC system, or a security light that won’t turn off are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your van’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This genuine GM-quality module, part number 10367690, is the definitive solution to restore your vehicle’s systems to factory-perfect operation.
From the Diagnostic Bay
We had a 2006 Savana 3500 work van come in with the weirdest set of symptoms. The driver said his dome lights would stay on, the radio would randomly shut off, and the power door locks had a mind of their own. He had already replaced the battery and checked all the fuses. After hooking up the scanner, we saw a dozen communication error codes all pointing back to the BCM. A faulty ground or wiring issue can sometimes mimic these symptoms, but a quick check confirmed the wiring was solid. The internal circuitry of the original BCM had simply failed. We installed a VIN-programmed module, and within 10 minutes, every single issue was resolved. The customer was thrilled to have his reliable workhorse back without the electrical gremlins.
Symptoms of a Failing Savana 3500 BCM
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ HVAC blower motor or climate controls not working properly.
- ✔ Vehicle security system acting up, potentially causing a no-start condition.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Intermittent operation of windshield wipers.
- ✔ Multiple communication-related Diagnostic Trouble Codes (DTCs) stored in the system.
The Plug-and-Play Advantage: VIN Programming Included
Don’t waste time and money at the dealership. We pre-program this Body Control Module to your van’s specific Vehicle Identification Number (VIN) before shipping. This crucial step ensures that the module communicates flawlessly with your vehicle’s other electronic systems right out of the box. It’s a true plug-and-play solution that eliminates the need for expensive dealer-only programming tools, getting you back on the road faster.
This module is a direct replacement and interchanges with a wide range of part numbers, including: 15116066, 10383536, 15136225, 15136877, 15137393, 15137394, 15137395, 15137396, 15198116, 15257043, 15257044, 15257045, 15257046, 15064149, and 15194170.
Installation and Post-Install Notes
Installation is straightforward for the DIY mechanic. The BCM in the Savana van is typically located in the center dash area. Simply disconnect the vehicle’s battery, remove the old module, plug in your new pre-programmed unit, and reconnect the battery. In most cases, no further action is needed. However, please be aware of a few potential post-installation procedures:
- Airbag System Sync: If the airbag light remains on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and stability control function.
Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any extra fees or hassle.
What does ‘VIN Programmed’ mean?
It means we load your vehicle’s specific VIN and factory settings onto the module before it ships. This makes it ready for installation without needing a trip to the dealership for expensive programming.
Where is the BCM located on my 2005 Savana 3500?
On the 2004-2007 Savana and Express vans, the BCM is located behind the center dash panel, often near the HVAC controls.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause for the B1001 code. Replacing it often resolves the issue, but you may need to perform the ‘Setup SDM Primary Key’ procedure with a scan tool after installation to turn the light off.
Is this part compatible with other GM trucks and SUVs?
Yes, this BCM is compatible with a wide range of 2002-2007 GM vehicles, including Silverado, Sierra, Tahoe, Yukon, Suburban, Escalade, and Hummer H2 models. Always verify the part number for your specific application.
