Are you battling frustrating electrical problems in your 2004-2007 GMC Savana 3500 Van? Intermittent wipers, flickering lights, a dead HVAC system, or a security light that prevents your workhorse from starting are all classic signs of a failing Body Control Module (BCM). As the electronic nerve center for your van’s body functions, when the BCM goes down, it can bring your work to a grinding halt. This isn’t just an inconvenience; it’s lost time and money.
Instead of paying for expensive dealership diagnostics and programming, our expert Cloning Service offers a fast, reliable, and cost-effective solution. We transfer the exact data from your original BCM to a fully tested replacement unit. This means the replacement module is a perfect electronic match for your vehicle, preserving all your original settings and security information. The result is a true plug-and-play fix—no additional programming or calibration required.
From the Diagnostic Bay
I remember a fleet manager who brought in a 2006 Savana 3500 that was becoming a real nightmare. One day the power locks wouldn’t work, the next the radio was dead, and sometimes it just wouldn’t start at all. His mechanics had already replaced the battery and checked all the grounds. After hooking up my scanner, I saw a handful of communication loss codes (U-codes) pointing to the BCM. These modules, especially in hard-working vans, often fail from years of thermal stress and voltage fluctuations. We performed a cloning service, and the van was back in his fleet the next day, running without a single glitch. It’s a common story, and this service is the most efficient fix I’ve found in 20 years.
Is Your Savana Showing These Electrical Gremlins?
A faulty BCM can cause a wide range of confusing symptoms. If you’re experiencing any of the following, your 2004-2007 Savana 3500 BCM is the likely culprit:
- ✔ Non-functional or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or stays stuck on high.
- ✔ The security or anti-theft light is on, causing a no-crank or no-start condition.
- ✔ An illuminated airbag light, often accompanied by Diagnostic Trouble Code (DTC) B1001 (Option Configuration Error).
- ✔ Unpredictable behavior from the windshield wipers or radio.
- ✔ False warning messages appearing on the instrument cluster.
Simple Swap-Out: Your 5-Minute Installation Guide
Getting your Savana back on the road is straightforward. No complex procedures or special tools are needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: In the 2004-2007 Savana Van, the BCM is typically found in the center of the dashboard, accessible from below. It’s a black plastic box with several large electrical connectors.
- Swap the Module: Carefully unplug the wiring harness connectors from your old BCM. Remove the module from its mounting bracket and set the new, cloned module in its place.
- Reconnect and Test: Securely plug the wiring harnesses into the new BCM. Reconnect the battery terminal, start the vehicle, and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Important Note: In some cases, post-installation procedures like an Airbag System Sync or a Brake Pedal Position Relearn may be necessary. Please see our FAQ for more details.

Frequently Asked Questions
What exactly is a BCM cloning service?
Our cloning service is a process where we transfer all the critical, vehicle-specific programming from your original, failing BCM to a fully functional replacement module. This includes the VIN, security data, and all option configurations, making the new module a perfect electronic duplicate.
Do I need to take my van to a dealer for programming after installation?
No. Because we clone your original data, the replacement BCM is ready for immediate installation. It’s a true plug-and-play solution that saves you the time, cost, and hassle of a dealership visit.
Where is the BCM located on my 2005 Savana 3500?
On the 2004-2007 Savana and Express vans, the Body Control Module is located behind the center dash panel, often near the HVAC controls. Access is typically from underneath the dashboard.
What if my airbag light comes on after I install the new BCM?
This is uncommon, but if it happens, it means the BCM and the airbag’s Sensing and Diagnostic Module (SDM) need to be re-synced. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a professional technician with a capable diagnostic scan tool.
Do I need to send my old part back? Will I get it back?
Yes, you must send us your original module for the cloning service. We always return your original module to you along with the newly programmed replacement unit. We do not keep your old part.
