Restore Full Electrical Function to Your GM Truck or SUV
Are you battling strange and frustrating electrical problems in your Chevrolet Silverado, GMC Sierra, or other GM vehicle? Flickering lights, unresponsive power windows, a dead HVAC blower, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of seemingly unrelated issues. This VIN-programmed BCM, part number 15064149, is the definitive solution to restore your vehicle’s systems to perfect working order.
From the Diagnostic Bay
We recently had a 2005 Silverado 2500 in the shop that was driving its owner crazy. The radio would turn on and off by itself, the driver’s side power window worked only intermittently, and the air conditioning would randomly stop blowing. The owner had already replaced the battery and checked all the fuses. A quick scan revealed multiple communication error codes pointing to the BCM. After installing one of our VIN-programmed modules, every single issue was resolved instantly. The customer was thrilled to have his truck back to normal without a costly trip to the dealership.
Common Symptoms of a Failing Silverado 3500 Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a replacement module is likely the solution:
- ✔ Unresponsive or erratic power windows, door locks, or interior lights.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or climate controls that don’t work.
- ✔ An illuminated airbag warning light, often accompanied by DTC B1001.
- ✔ Security system malfunctions, including a no-start condition where the engine won’t crank.
- ✔ Inconsistent windshield wiper operation.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs).
Plug-and-Play Installation with VIN Programming
The biggest hurdle in replacing a BCM is the need for expensive dealership programming. We eliminate that step entirely. Simply provide your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your truck. This ensures it works seamlessly right out of the box. Installation is straightforward and can typically be done in under 15 minutes with basic hand tools. The BCM is usually located under the driver’s side dashboard, near the steering column.
Post-Installation Notes
While this module is designed for plug-and-play operation, some vehicles may require a simple relearn procedure. If your airbag light remains on after installation, a technician with a professional scan tool will need to perform the “Setup SDM Primary Key in BCM” function to sync the systems. This is a quick procedure that finalizes the installation. No core charge is required, so you can keep your old part without any hassle.

Frequently Asked Questions
What does a Body Control Module do on a 2003-2007 Silverado?
The BCM is a computer that manages and controls many of the non-engine related electronic functions in your truck, such as the power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC controls.
Do I need to get this part programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This allows for a simple, plug-and-play installation without the need for any additional programming at a dealership.
Is this BCM difficult to install?
Installation is generally simple for someone with basic mechanical skills. It’s located under the driver’s side dash and is held in place by a few clips or bolts. Disconnecting the battery and swapping the module usually takes less than 15 minutes.
What if my airbag light is on after I install the new BCM?
If the airbag light is on, it means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A technician with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my truck’s no-start problem?
If the no-start condition is caused by the factory anti-theft or security system, which is controlled by the BCM, then yes, replacing the module will likely solve the problem.
