Restore Full Functionality to Your GM Vehicle
Are you battling frustrating electrical problems in your work van or truck? A faulty Body Control Module (BCM) is often the culprit behind a cascade of issues that can bring your vehicle to a standstill. As the central command for your vehicle’s body electronics, a failing BCM can cause everything from flickering lights and a dead HVAC system to a no-start condition. This replacement BCM, equivalent to OEM part number 15136225, is the definitive solution for your 2004-2007 Savana 3500 Van and a wide range of other GM vehicles. We pre-program it to your specific VIN, ensuring it works right out of the box without a trip to the dealership for expensive programming.
Case Study: The Ghost in the Machine
I had a 2006 Savana 3500 work van come into my bay that was a diagnostic nightmare for another shop. The driver reported intermittent no-start, the radio would cut out, and an airbag light was on with a DTC B1001 (Option Configuration Error). They had already replaced the battery and checked grounds. The previous tech was convinced it needed a new SDM (airbag module). After checking the network communication, I noticed data dropouts from the BCM. A failing BCM can disrupt communication with other modules, setting false codes elsewhere. We installed one of our VIN-programmed BCMs, and all the ghost-like symptoms vanished instantly, including the B1001 code. It’s a classic example of how a single failing component can create widespread, confusing issues.
Is Your Vehicle Showing These Signs of BCM Failure?
- ✔️ Intermittent or non-working power windows, door locks, or interior lights.
- ✔️ HVAC blower motor or climate controls not functioning correctly.
- ✔️ The security system acts erratically, causing a no-start or crank-no-start condition.
- ✔️ An airbag warning light is illuminated, often with communication codes like B1001.
- ✔️ Unpredictable electrical behavior, such as wipers turning on by themselves.
- ✔️ A cluster of seemingly unrelated Diagnostic Trouble Codes (DTCs).

A Straightforward Guide to Your BCM Replacement
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the Module: On Savana and Express vans, the BCM is typically found in the center of the dash. On most trucks and SUVs, it’s located under the driver’s side dash, near the steering column.
- ✔ Swap the Connectors: Carefully unplug the electrical connectors from the old BCM and transfer them to your new, pre-programmed module. The connectors are color-coded and keyed to prevent mistakes.
- ✔ Secure the New BCM: Mount the new module in the same position as the old one.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all body functions: lights, locks, windows, wipers, and HVAC to confirm the repair is successful.
Post-Installation Note: In some cases, particularly if the airbag light was on, a procedure called “Setup SDM Primary Key in BCM” may be needed using a professional scan tool to sync the BCM with the airbag system. This is only required if the airbag light remains on after installation.

Frequently Asked Questions
Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any extra fees.
Is any special programming required after installation?
This BCM comes fully programmed to your VIN. In most cases, it is a simple plug-and-play installation. The only exception may be an airbag system sync (‘Setup SDM Primary Key’) if the airbag light remains on, which requires a professional scan tool.
Will this fix my no-start problem?
If your no-start issue is caused by the BCM’s control over the vehicle’s security system (Passlock/VATS), then replacing it with this programmed module should resolve the problem. However, no-start can have many causes, so proper diagnosis is key.
What tools do I need to install this?
Typically, only basic hand tools like a socket set or screwdriver are needed to access the module under the dash. No special electronic tools are required for the physical installation.
What does ‘w/commercial tradesman package (opt PRP)’ mean for my Savana van?
This refers to a specific factory option package (RPO code PRP) on Express and Savana vans that affects the BCM configuration. Our VIN programming process automatically accounts for this and all other options your van was built with, ensuring perfect compatibility.
