Restore Full Control Over Your GM Vehicle’s Electronics
If your 2004-2007 GMC Savana 1500 or other compatible GM truck is plagued by baffling electrical problems, the Body Control Module (BCM) is the most likely culprit. As the central command for your vehicle’s body electronics, a failing BCM can cause a cascade of frustrating and unpredictable issues. This OEM-quality replacement, part number 15137394, is the reliable solution to restore order. It governs everything from your power windows and door locks to the HVAC system and interior lighting. Instead of spending a fortune at the dealership, our unique cloning service makes this a straightforward, cost-effective repair you can trust.
A Technician’s Notebook: The Contractor’s Savana with a Mind of Its Own
A local electrician brought his ’06 Savana 2500 work van into my bay with a list of symptoms that sounded like a poltergeist. The dome lights would flicker randomly, the radio would shut off, and worst of all, the van would intermittently refuse to start, costing him time and money on jobs. His scan tool showed a mess of communication codes. After checking the main grounds and power feeds to the BCM, it was clear the module itself was failing internally. We used our cloning service to transfer the data from his original, faulty BCM to our replacement unit. He had the new module back in two days, plugged it in himself in the parking lot, and the van fired right up with zero issues. All the strange electrical gremlins were gone. It’s a perfect example of how a quality 2004-2007 Savana 1500 BCM can be the key to getting a critical work vehicle back in service fast.
What is Our BCM Cloning Service?
This isn’t just a part; it’s a complete solution. Our cloning service eliminates the need for expensive dealership programming. Here’s how it works: you send us your original BCM, and we perform a professional, bench-level data transfer. We copy the vital information—like your vehicle’s specific options, security settings, and VIN—directly to this replacement module. We then ship both your original module and the ready-to-install replacement back to you. This ensures seamless integration and preserves all your vehicle’s original functionality without any extra steps. There is no core charge, and you always get your original part back.
Are You Experiencing These Common BCM Failure Signs?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s time to consider a replacement:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security system light stays on, or the vehicle won’t start (anti-theft issue).
- ✔ An airbag warning light on the dash, often accompanied by DTC B1001 (Setup SDM Primary Key in BCM).
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs) pointing to communication errors.
A Straightforward Guide to Installation
Replacing the BCM is a simple process that most DIYers can complete in minutes. For the 2004-2007 Savana 1500 BCM, the module 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: On Savana and Express vans, it’s usually behind a panel in the center dash area. On trucks and SUVs, it’s often under the driver’s side of the dashboard, near the steering column.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding it in place.
- Install the New Module: Seat the new, cloned BCM in the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, locks, windows, wipers, and the HVAC system to confirm the repair was successful.
In some cases, particularly if the airbag light was on, a post-installation procedure like an ‘SDM Key Setup’ or ‘Brake Pedal Position Relearn’ may be needed with a high-end scan tool. However, our cloning service drastically reduces the likelihood of requiring these extra steps.

Frequently Asked Questions
How exactly does the BCM cloning service work?
You place your order, and we provide you with instructions to ship your original BCM to us. Our technicians then use specialized equipment to read the unique data from your module and write it directly onto the replacement unit. We then ship both modules back to you, ensuring the replacement is 100% plug-and-play.
Will I need a mechanic or a dealership to program this part?
No. The primary benefit of our cloning service is that it completely eliminates the need for any additional programming. The module arrives ready for installation, saving you hundreds of dollars in dealership fees.
What does the Body Control Module (BCM) actually do?
The BCM acts as the brain for your vehicle’s body-related electronic accessories. It controls functions like interior and exterior lighting, power windows and locks, the alarm system, wipers, and the heating and A/C system. When it fails, these systems can become unreliable.
Is it possible I will still need a scan tool after installing the cloned BCM?
While our cloning service minimizes the need for it, there’s a small chance a post-install procedure might be necessary. For example, if the airbag light is on, an ‘SDM Primary Key Setup’ may be required to sync the airbag system to the new BCM. This requires a professional-grade diagnostic tool.
Do I need to return my old part? Is there a core charge?
You need to send us your original module for the cloning service, but there is no core charge. We always return your original BCM along with the programmed replacement.
