Restore Your Van’s Electrical System with a Reliable BCM
Are you battling perplexing electrical issues in your 2004-2007 GMC Savana 1500 Van? When features like your power windows, door locks, or interior lights start acting erratically or stop working altogether, the Body Control Module (BCM) is often the culprit. As the nerve center for your vehicle’s body electronics, a failing BCM can cause a host of frustrating problems that can take your work van off the road. This replacement BCM, part number 15198116, is the definitive solution to restore full functionality and reliability to your vehicle.
We make the repair process straightforward with our professional cloning service. Simply send us your original BCM, and we will transfer all the critical vehicle-specific data to this replacement unit. This means no expensive trips to the dealership for programming. The module arrives at your door ready for a plug-and-play installation, getting your Savana back in service quickly and efficiently. It’s the most effective way to solve complex electrical problems without the hassle.
Case Study: A Tricky Diagnosis
I remember a fleet customer who brought in a 2006 Savana 2500 work van. The complaint was intermittent no-start and the security light flashing randomly. They had already replaced the battery and checked the starter. Diagnostics showed a loss of communication with various modules at random intervals. After checking the main power and ground circuits, we focused on the BCM. These modules are known to fail internally, causing grounding issues within the circuit board itself. By swapping in a cloned BCM, we resolved not only the no-start but also a flickering dome light the driver hadn’t even mentioned. This is a classic failure scenario for these hardworking vans.
Diagnosing a Faulty 2004-2007 Savana 1500 BCM
A failing Body Control Module can manifest in ways that might seem unrelated. If you’re a professional technician or a hands-on van owner, recognizing these signs is the first step toward a correct diagnosis. A faulty BCM doesn’t just inconvenience you; it can compromise your vehicle’s security and safety systems. Getting it fixed promptly is essential.
Common Signs of a Failing Savana BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or that flicker intermittently.
- ✔ The security system acting up, causing a no-start condition or the alarm to go off unexpectedly.
- ✔ HVAC controls not responding or the blower motor working only on certain speeds.
- ✔ An airbag warning light on the dash, sometimes accompanied by DTC B1001 (Option Configuration Error).
- ✔ Communication loss codes with other modules stored in the vehicle’s computer system.
A Straightforward Guide to Installation
Replacing the BCM in your Savana is a simple process that can be done with basic hand tools. Our cloning service ensures the module is ready to install right out of the box.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: In most 2004-2007 Savana and Express vans, the BCM is located in the center of the dashboard, often behind a lower access panel.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM into the mounting bracket and securely plug in all the electrical connectors. You should 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 body functions—lights, locks, windows, wipers, and HVAC—to confirm the repair was successful.

Frequently Asked Questions
What is the cloning service and why do I need it?
Your van’s original BCM contains security information and vehicle-specific options programmed to your VIN. Our cloning service transfers this exact data to the replacement module. This makes the installation plug-and-play and avoids the need for expensive dealership programming.
Do I need to send my old BCM to you?
Yes. For the cloning service to work, we need your original module to extract the necessary data. We will perform the service and ship both your original module and the ready-to-install replacement back to you.
Is there a core charge for this part?
No, there is no core charge. We always return your original module along with the newly programmed replacement, so you don’t have to worry about extra fees or returning a core later.
Why is my airbag light on after installing the new BCM?
This can happen if the BCM and the Sensing and Diagnostic Module (SDM) lose their sync. A professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick relearn that restores communication and turns off the light.
What tools do I need for installation?
Basic hand tools like a socket set or screwdriver are typically all that’s required to access and remove the BCM. No special electronic tools are needed for the installation itself, thanks to our cloning service.
Will this fix my van’s no-start problem?
If the no-start is caused by the security system (Passlock/Passkey) being controlled by a faulty BCM, then yes, this part is very likely to solve the issue. It’s a common failure point that our cloned BCMs are designed to fix.
