End Electrical Headaches in Your GM Van or Truck
Are you chasing down bizarre electrical issues in your 2004-2007 Savana 1500 Van? One minute the A/C works, the next it doesn’t. Maybe the power locks have a mind of their own, or a persistent airbag light refuses to go away. These are classic signs of a failing Body Control Module (BCM). This module, part number 15136877, is the central command for your vehicle’s body electronics. When it falters, it can create a cascade of frustrating and seemingly unrelated problems. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle.
The Power of Our Cloning Service
Forget about expensive dealership visits and complex programming tools. Our unique Cloning Service makes this repair straightforward for any DIY enthusiast or professional mechanic. Simply send us your original BCM, and we will expertly transfer its specific data—including key information, security settings, and vehicle options—directly to this replacement unit. The module you receive will be a perfect electronic match for your van, ensuring a true plug-and-play installation. This process for your 2004-2007 Savana 1500 BCM preserves all original functions without any extra steps.
From the Diagnostic Bay
I remember a 2006 Savana 2500 work van that came into my shop. The owner, a local plumber, was at his wit’s end. The van would intermittently refuse to start, the dome lights would flicker, and the radio would randomly turn off. He had already replaced the battery and checked the alternator. After hooking up my scanner, I saw a handful of communication loss codes pointing to the BCM. A quick check of the BCM’s power and ground connections confirmed my suspicion: the module had an internal failure. By providing a cloned BCM, we had him back on the road to his next job in under an hour, completely solving all the ghost-like electrical issues. These modules are workhorses, but when they fail, the symptoms can be confusing. A direct, properly programmed replacement is always the right fix.
Is Your Savana Van Showing These BCM Failure Signs?
- âś” Intermittent or non-working HVAC and blower motor controls.
- âś” An active airbag warning light, often with a Diagnostic Trouble Code (DTC) like B1001 (Option Configuration Error).
- âś” Unresponsive power windows, door locks, or interior/exterior lights.
- âś” Security system problems, including no-start conditions where the engine won’t crank.
- âś” Strange electrical behavior, like the radio turning on or off by itself.
- âś” Poor communication between various vehicle modules.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal on your vehicle’s battery before starting any electrical work.
- âś” Locate the BCM: In the Savana and Express vans, the BCM is typically located in the center of the dashboard, often accessible by removing a lower dash panel.
- âś” Swap the Module: Carefully unplug the electrical connectors from your old BCM. They have locking tabs that need to be depressed. Plug them securely into your new, cloned BCM.
- âś” Final Steps: Re-install the BCM and any panels you removed. Reconnect the battery terminal. Start the vehicle to confirm all functions are restored.
Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM systems may require a quick sync. If your airbag light remains on after installing the new 2004-2007 Savana 1500 BCM, a professional scan tool will be needed to perform the “Setup SDM Primary Key in BCM” procedure. In some cases, a Brake Pedal Position Relearn may also be required. Your original module will be returned to you with the replacement unit; there is no core charge.

Frequently Asked Questions
Frequently Asked Questions
What exactly is the “Cloning Service”?
Cloning is a process where we transfer the vital configuration and security data from your original BCM directly onto the replacement module. This makes the new part an exact electronic copy, ensuring it works immediately upon installation without needing a trip to the dealer for programming.
Do I need to send my original module to you?
Yes, for the cloning service to be successful, you must send us your original Body Control Module. We will perform the service and ship both your original and the newly programmed replacement back to you.
Will this fix my airbag light that is on?
It can. If the airbag light is caused by a BCM communication error (like DTC B1001), this will solve the root cause. However, after installation, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and clear the light.
Can I install this part myself?
Absolutely. For most DIYers with basic tools, this is a very manageable job. The module is typically easy to access, and our cloning service eliminates the most difficult step: programming.
Is there a core charge for this part?
No, there is no core charge. We require your original module for the cloning service and will return it to you along with the replacement part.
What kind of warranty is included?
This BCM is backed by our one-year warranty, giving you peace of mind and confidence in your repair.
