Restore Full Functionality to Your Work Van
Are you battling frustrating electrical issues in your 2004-2007 GMC Savana 1500? Flickering lights, unresponsive power windows, a dead HVAC blower, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). The BCM is the central command for your van’s body electronics, and when it fails, it can cause a cascade of problems that disrupt your workday and compromise your vehicle’s reliability. This replacement BCM, part number 15194170, is the definitive solution to restore order and get your van back to being a dependable workhorse.
What makes our module different is our expert Cloning Service. Instead of a generic programming that might require multiple follow-up procedures at a dealership, we transfer the precise data from your original BCM directly to this replacement unit. This creates a perfect digital copy, ensuring all your van’s specific options and security settings are preserved. The result is a true plug-and-play installation that saves you time, money, and the headache of a trip to the service bay.
Case Study: A Tricky Diagnosis
A local contractor brought in his ’06 Savana 1500 with a bizarre set of symptoms. The radio would turn on by itself, the driver’s side power lock was dead, and the A/C blower only worked on high. He had already replaced the blower motor resistor with no luck. After connecting my scanner, I saw a handful of communication codes (U-codes) and a B1001 DTC. In my 20+ years of experience, these ghost-in-the-machine issues almost always point back to the BCM. The internal relays and solder joints on these modules, especially in hard-working vans, fatigue over time. We performed our cloning service on a replacement 2004-2007 Savana 1500 BCM, and the install took him less than 10 minutes in our parking lot. All issues were resolved instantly—no relearn procedures needed.
Is Your Savana Showing These Symptoms?
- ✔ The HVAC blower motor is intermittent or only works on certain speeds.
- ✔ Power windows, door locks, or interior dome lights operate erratically or not at all.
- ✔ The anti-theft or security light stays on, sometimes causing a no-start condition.
- ✔ An airbag warning light is illuminated, often with a DTC like B1001 (Option Configuration Error).
- ✔ Wipers or exterior lights function incorrectly.
- ✔ Communication errors (U-codes) are present when scanning the vehicle.
A Straightforward Guide to Installation
Thanks to our cloning service, installing your replacement 2004-2007 Savana 1500 BCM is a simple process that most DIYers can complete quickly. In these vans, the BCM is typically located in the center of the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: Find the module in the center dash area. You may need to remove a lower dash panel for access. It will have several large electrical connectors attached.
- Swap the Modules: Carefully unplug the wiring harnesses from your old BCM. Unbolt or unclip the module from its mounting bracket and remove it. Place the new, cloned BCM into the bracket and securely reconnect all wiring harnesses.
- Reconnect and Test: Reconnect the negative battery terminal. Start the van and test all functions—lights, locks, windows, HVAC, and wipers—to confirm the repair was successful.

Frequently Asked Questions
How does the cloning service work?
After you place your order, you will send us your original Body Control Module. Our technicians will then extract the unique vehicle data and security information and flash it directly onto your new replacement module. This ensures 100% compatibility with your van’s specific features.
Do I get my old module back?
Yes, your original module is always returned to you along with the programmed replacement unit. We do not keep the core, and there is no core charge.
Will I need a scan tool after installation?
In most cases, no. Because we clone your original data, the need for post-installation procedures is greatly reduced. However, if an airbag light appears, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure.
What if my airbag light is on after installing the new BCM?
This can happen occasionally. It requires a professional diagnostic tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, which syncs the airbag system (SDM) with the new BCM and turns off the light.
Is a Brake Pedal Position Relearn required?
While our cloning service minimizes the need for this, some models may still require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation. This can typically be done with a capable bi-directional scan tool.
