Solve Erratic Electrical Issues in Your 2004-2007 GMC Savana 1500
Is your work van suddenly plagued by bizarre electrical problems? Flickering lights, a dead instrument cluster, or a security system that prevents the engine from starting can sideline your vehicle and your business. These are classic signs of a failing Body Control Module (BCM). This replacement module, part number 15136225, is the definitive solution for your Savana 1500 Body Control Module issues. Through our expert cloning service, we transfer your van’s unique configuration from your old BCM to this replacement unit, making installation a true plug-and-play process without any need for expensive dealership programming.
The BCM is the central command for your van’s comfort and security features, including power locks, windows, interior and exterior lighting, wipers, and the HVAC system. When it fails, it can create a cascade of frustrating, hard-to-diagnose symptoms. Our service is designed to get you back on the road quickly and reliably, restoring full functionality to the systems you depend on every day.
A Technician’s Notebook: The Case of the Unreliable Work Van
I once had a contractor bring in his ’05 Savana 2500. The complaint was intermittent no-starts and the radio staying on after he’d removed the key, draining the battery. He’d already replaced the battery and ignition switch to no avail. After hooking up my scanner, I saw a slew of communication and body-related DTCs. In my experience, especially with work vans that endure constant vibration and temperature swings, the BCM is a common point of failure. The solder joints on the board can develop micro-fractures over time. We performed our cloning service on a replacement BCM, and he was back on the road the next day. It’s a perfect example of how a targeted repair to the Savana 1500 Body Control Module can save hundreds in diagnostic fees and unnecessary parts.
Is Your Savana Exhibiting These Electrical Gremlins?
- ✔ The security or anti-theft light stays on, causing a no-start or crank-no-start condition.
- ✔ Power windows, door locks, or mirrors work intermittently or not at all.
- ✔ The HVAC blower motor is unresponsive, or the climate controls are inoperative.
- ✔ The airbag warning light is illuminated, often with a DTC like B1001 (Option Configuration Error).
- ✔ Interior dome lights or exterior lights flicker, stay on, or won’t turn on.
- ✔ The radio or other accessories don’t power down correctly after turning off the vehicle.
5-Minute BCM Swap: A Savana Owner’s Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and reset the system.
- ✔ Locate the Module: In the 2004-2007 Savana Van, the BCM is typically found in the center of the dashboard, often accessible after removing a lower dash panel.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Once disconnected, remove the module from its mounting bracket.
- ✔ Install the New BCM: Seat the replacement module into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- ✔ Power Up: Reconnect the negative battery terminal. Your van’s essential body functions should now be fully restored.
Important Post-Installation Note: In some cases, you may need a professional scan tool to perform a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on, or a ‘Brake Pedal Position Relearn’. This syncs the related safety systems with the new BCM. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a process where our technicians extract the essential vehicle-specific data (like VIN, mileage, and security information) from your original, faulty BCM and flash it directly onto the replacement module. This makes the new part recognize your vehicle instantly, eliminating the need for dealership programming.
Where is the BCM located on my 2006 Savana 1500?
On most 2004-2007 Savana and Express vans, the Body Control Module is located behind the dashboard, in the center area, often near the HVAC controls. Access may require removing a lower dash panel.
Do I need to take my van to a dealer after installation?
No. Because this module is cloned with your van’s original data, it is a plug-and-play solution. This saves you the time, cost, and hassle of a trip to the dealership for programming.
My airbag light came on after I installed the new BCM. What should I do?
This can happen occasionally. It means the BCM and the airbag system’s Sensing and Diagnostic Module (SDM) need to be re-synced. A professional mechanic can perform the ‘Setup SDM Primary Key in BCM’ procedure with a bi-directional scan tool to resolve this and turn off the light.
Is there a core charge for this part?
No, there is no core charge. We require your original module to perform the cloning service, and we always return your original module to you along with the newly programmed replacement unit.
Will this fix my intermittent power locks and windows?
If the BCM is the root cause of the failure, then yes. The BCM directly controls the power lock and window circuits. This replacement will restore proper function to those systems.
