Restore Full Electrical Function to Your GM Van or Truck
Are you battling frustrating electrical problems in your GMC Savana, Chevrolet Express, or another GM truck? A faulty Body Control Module (BCM) is often the culprit behind issues like malfunctioning lights, unpredictable power windows and locks, erratic HVAC behavior, and even no-start conditions. This genuine OEM-quality BCM, part number 15136225, is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation.
The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of seemingly unrelated problems. Replacing it with a generic, unprogrammed part from a junkyard or auto parts store often leads to more headaches and a necessary trip to the dealership for expensive programming. We eliminate that step entirely. This module arrives at your door pre-programmed to your vehicle’s specific VIN, ensuring a true plug-and-play installation.
Diagnosing a Faulty 2004-2007 Savana Body Control Module
Identifying a failing BCM can be tricky, as its symptoms can mimic other component failures. However, if your vehicle is experiencing several of the issues below simultaneously, the BCM is the most likely cause. This is especially true for the 2004-2007 Savana 1500 Van and its sister platforms like the Silverado, Tahoe, and Express.
Common Symptoms of BCM Failure
- ✔ Intermittent or non-working interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ HVAC and climate control systems failing to respond or blowing air incorrectly.
- ✔ The security system acting up, causing false alarms or preventing the engine from starting.
- ✔ An active airbag warning light, often accompanied by diagnostic trouble code B1001.
- ✔ Unexplained battery drain while the vehicle is parked.
- ✔ Wipers that won’t turn on, off, or park in the correct position.

Frequently Asked Questions
Do I need to take this BCM to a dealer for programming?
No. We pre-program the module to your vehicle’s VIN before shipping. This allows for a simple plug-and-play installation without any need for expensive dealership tools or software.
Where is the BCM located on my 2005 GMC Savana?
On the 2004-2007 Savana and Express vans, the BCM is typically located in the center of the dash, often accessible by removing a lower dash panel. On most trucks and SUVs like the Silverado and Tahoe, it’s found under the steering column.
What if my airbag light is on after installation?
If the airbag light remains on, it means the new BCM needs to be synchronized with the vehicle’s SDM (Sensing and Diagnostic Module). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed with a professional-grade diagnostic scan tool.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your old module without any obligation to return it, making the process hassle-free.
Will this fix my intermittent no-start problem?
A failing BCM is a very common cause of security-related no-start conditions in these GM vehicles. If the security light is flashing and the engine won’t crank, this VIN-programmed module is a highly effective solution.
