Solve Your Van’s Electrical Headaches for Good
If you’re dealing with bizarre electrical issues in your GMC Savana or Chevrolet Express van, you know how frustrating it can be. One minute the air conditioning works, the next it’s dead. The power locks have a mind of their own, or worse, a security system fault leaves you stranded. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can wreak havoc. This module, compatible with part number 15137393, is the definitive solution, restored to full function through our expert cloning service.
We make the repair process simple. Instead of buying a new module and paying for expensive dealership programming, you send us your original BCM. We transfer all the critical data—including your vehicle’s specific VIN and security information—to this replacement unit. The result is a true plug-and-play module that is ready for installation the moment you receive it, preserving all your original factory settings and functions without any additional hassle. This is the most reliable way to replace a faulty 2004-2007 Savana 1500 BCM and restore your van’s dependability.
A Technician’s Notebook: The Work Van That Wouldn’t Cooperate
I remember a 2006 Savana 2500 from a local contractor that came into my bay with a list of complaints that seemed unrelated. The driver said the radio would cut out, the dome light would flicker, and sometimes the power door locks wouldn’t respond. He’d already replaced the battery and checked the main grounds. After hooking up my scanner, I saw a dozen communication codes (U-codes) pointing to the BCM. Water had wicked its way down the A-pillar and onto the module, causing internal corrosion. A new BCM from the dealer would have meant programming fees and vehicle downtime he couldn’t afford. We used a cloned BCM, and he was back on the road the next day with all issues resolved. It’s a textbook example of how a single module can cause widespread, confusing symptoms.
Is Your GM Van Showing These Symptoms?
- ✔️ The HVAC blower motor works intermittently or not at all.
- ✔️ Power windows, door locks, or interior lights operate erratically or have failed completely.
- ✔️ An airbag warning light is illuminated on the dash, often with a DTC like B1001.
- ✔️ The anti-theft or security system prevents the engine from starting.
- ✔️ You’re experiencing strange battery drain issues that are hard to trace.
- ✔️ Wipers or exterior lights function incorrectly or not at all.
A Straightforward Guide to Installation
Installing your cloned 2004-2007 Savana 1500 BCM is a quick job that most DIYers can handle in minutes. In these vans, 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, find the BCM in the center dash area. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. 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 onto the mounting bracket and plug in the connectors until they click securely into place.
- Reconnect and Test: Reconnect the battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, HVAC, etc.—to confirm the repair.
Post-Installation Notes: In some cases, especially if you had an airbag light, a procedure like ‘Setup SDM Primary Key in BCM’ may be needed using a professional scan tool. A Brake Pedal Position Relearn might also be required. These are not always necessary but are good to be aware of.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Our technicians will then extract the unique programming and security data from your module and flash it onto the replacement unit. This ensures 100% compatibility with your vehicle’s existing systems.
Do I need to send my old BCM in? What about a core charge?
Yes, this service requires your original module for the data transfer. There is no core charge, and we always return your original module along with the newly programmed replacement unit.
Will I need special tools for installation?
Basic hand tools like a socket set or screwdriver are typically all that’s needed to access and swap the module. No programming tools are required. However, if an airbag light appears after installation, a professional-grade scan tool will be needed to perform the ‘Setup SDM Primary Key’ procedure.
Is this BCM guaranteed to fix my problem?
This module will correct issues directly caused by a faulty BCM. It’s crucial to properly diagnose the problem first, as similar symptoms can sometimes be caused by wiring or grounding issues. If your vehicle matches the symptoms and fitment, this is a highly reliable solution.
