Restore Full Electrical Function to Your 2004-2007 GMC Savana 1500 Van
Is your work van or family hauler suffering from bizarre electrical issues? One moment the power locks don’t work, the next the A/C blower quits, or a security light flashes for no reason. These frustrating, intermittent problems often point to a single culprit: a failing Body Control Module (BCM). This replacement BCM, part number 15064149, is the definitive solution for your 2004-2007 Savana 1500 BCM, restoring the reliable performance you depend on every day.
The BCM is the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of confusing symptoms. Instead of spending hundreds at a dealership on diagnostics and programming fees, we offer a simple, cost-effective solution. Our professional cloning service transfers all the critical data from your original module to this replacement unit. The result is a true plug-and-play part that requires no additional programming upon arrival. Get your van back to work without the hassle.
A Technician’s Notebook: The Case of the Contractor’s Van
I had a 2006 Savana 2500 work van come into my bay last month that was driving the owner, a local plumber, crazy. The radio would turn on and off by itself, the driver’s side power window was dead, and the HVAC blower motor was intermittent. He had already replaced the blower motor resistor to no avail. After hooking up my scan tool, I found a slew of communication DTCs and a B1001 code. In my 20 years of experience, seeing multiple, unrelated body system failures like this on a GM van almost always leads back to the BCM. We swapped in a cloned module, and every single issue was resolved instantly. It’s a common failure point, especially on vans that see hard use.
Is Your Savana Van Showing These Electrical Faults?
- ✔ The HVAC blower motor works intermittently or not at all.
- ✔ Power windows, door locks, or interior dome lights fail to operate correctly.
- ✔ An airbag warning light is illuminated on the dash, often with a DTC like B1001.
- ✔ The anti-theft or security system acts up, sometimes causing a no-start condition.
- ✔ Headlights, taillights, or turn signals behave erratically.
- ✔ You’re chasing multiple body-related diagnostic trouble codes (DTCs) with no clear cause.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the Module: In the 2004-2007 Savana and Express vans, the BCM is typically located behind the center dash panel, often near the radio. You may need to remove some trim pieces for access.
- ✔ Swap the Connectors: The BCM has several multi-pin electrical connectors. Carefully press the release tabs and disconnect them from your old module. Plug them securely into the corresponding ports on your new, cloned BCM.
- ✔ Secure the New Module: Mount the new BCM in the same position as the old one.
- ✔ Power Up and Test: Reconnect the battery terminal. Start the vehicle and test all the functions that were previously failing—windows, locks, HVAC, lights, etc.
Post-Installation Note: In some cases, you may need a professional scan tool to perform an “Airbag System Sync” (Setup SDM Primary Key in BCM) if the airbag light remains on, or a “Brake Pedal Position Relearn.” This is vehicle-dependent. Always refer to a factory service manual for specific procedures.

Frequently Asked Questions
What is a cloning service?
Cloning is a process where we transfer the essential vehicle-specific data—including the VIN, mileage, and security information—from your original BCM to the replacement unit. This ensures the new module is perfectly synced with your vehicle’s other systems, making it a true plug-and-play solution without needing a trip to the dealer for programming.
Do I need to send my original BCM to you?
Yes. For our cloning service to work, you must send us your original module after placing your order. We will perform the service and ship both your original and the newly programmed replacement back to you. We do not keep your original part.
Will this fix my airbag light?
If the airbag light is on due to a BCM communication fault (like DTC B1001), this module will likely resolve the root cause. However, after installation, the airbag system may need to be re-synced using a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Is this hard to install myself?
For someone with basic mechanical skills, the installation is very straightforward. It primarily involves removing a few dash trim panels and swapping electrical connectors. The entire process can often be completed in under 30 minutes.
What if I have the wrong part number?
This BCM is interchangeable with a long list of part numbers, including 15116066, 15136225, and 15064149. As long as your vehicle is on the compatibility list and your original part looks identical, this module will work. If you’re unsure, contact our expert support team with your VIN.
