Is your 2003-2007 GM truck or SUV suffering from strange and frustrating electrical problems?
You’re not alone. The Body Control Module, or BCM, is the central nervous system for your vehicle’s comfort and convenience features. When it begins to fail, it can cause a cascade of issues that seem unrelated, from flickering lights and malfunctioning power windows to a dead instrument cluster or even a no-start condition. This replacement Body Control Module, part number 15137395, is the definitive solution for restoring full electrical functionality to your vehicle.
Specifically designed as a direct-fit replacement for models like the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, and Cadillac Escalade, this module arrives expertly programmed to your vehicle’s specific VIN. This means no expensive trips to the dealership for programming—it’s a true plug-and-play repair that gets you back on the road fast.
We had a 2005 Silverado 2500 in the shop that was driving its owner crazy. The radio would change stations on its own, the dome light wouldn’t turn off, and occasionally the power locks would stop working entirely. He had already replaced the battery and checked all the fuses. After a quick scan, we found multiple communication error codes pointing to the BCM. We installed one of our VIN-programmed modules, and in less than 10 minutes, every single ghost in his machine was gone. It’s a common failure, and having a pre-programmed module is the fastest, most reliable fix.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ HVAC and climate control systems behaving erratically or not at all.
- ✔ An illuminated airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Security system malfunctions, leading to a no-start or crank-no-start situation.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on.
- ✔ Unpredictable behavior from the radio, wipers, or instrument cluster.
Why Choose Our Pre-Programmed 2003-2007 Silverado BCM?
This isn’t just a replacement part; it’s a complete solution. We take the guesswork and extra cost out of the repair process. By programming the module with the latest GM software updates matched to your VIN before it ships, we ensure it communicates flawlessly with your truck’s other electronic systems right out of the box. This module is built to meet or exceed original equipment standards for lasting durability and performance.
Installation is straightforward, typically located under the driver’s side dash near the steering column. Simply disconnect the battery, swap the modules, and reconnect. While the unit is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. There is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the main computer for your truck’s body electronics. It controls functions like power windows, locks, interior/exterior lights, the security system, wipers, and HVAC blower speeds.
Is this BCM difficult to install?
No, installation is typically very simple and takes under 10 minutes. The BCM is usually located under the steering column. You just need to disconnect the battery, unplug the old module, plug in the new one, and reconnect the battery.
Do I need to take my truck to the dealer after installing this?
No. This module comes pre-programmed to your vehicle’s VIN, eliminating the need for costly dealership programming. It’s designed for a plug-and-play installation.
What does ‘VIN Programmed’ mean?
It means we load the module with your truck’s specific software and settings using your Vehicle Identification Number (VIN) before we ship it. This ensures it works correctly with all the specific options your vehicle was built with.
Will this fix my airbag light with a B1001 code?
A faulty BCM is a very common cause of an airbag light with code B1001. Replacing it often resolves the issue. In some cases, a post-installation procedure with a scan tool is needed to sync the new BCM with the airbag system (SDM).
This part is interchangeable with many numbers, does that matter?
No, the part numbers listed (like 15116066, 15137395, etc.) are often hardware revisions. Our programming ensures that no matter the hardware number, the module will function correctly for the entire compatible vehicle range.
