Restore Full Electrical Function to Your Truck
Are you battling frustrating electrical gremlins in your GMC Sierra or Chevrolet Silverado? Intermittent wipers, flickering lights, unresponsive door locks, or a malfunctioning HVAC system are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your truck’s body electronics, and when it fails, it can cause a cascade of confusing and unpredictable issues. This genuine quality Body Control Module, part number 25971917, is the definitive solution for your 2007-2013 GM truck or SUV, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
From the Diagnostic Bay
We had a 2008 Silverado 2500 in the shop that was driving the owner crazy. The radio would cut out, the dome lights would stay on, and the power windows worked only when they wanted to. The customer was convinced he needed a new BCM. Before swapping the part, we did a full systems check and found a corroded ground strap on the frame rail just below the driver’s door. After cleaning the connection point and replacing the strap, all the issues vanished. While a faulty BCM was a likely culprit, this case was a reminder: always check your main power and ground connections before replacing expensive modules. A poor ground can mimic the symptoms of a failed BCM perfectly.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ HVAC and climate control systems not responding or blower motor issues.
- ✔ Vehicle security system malfunctions or false alarms.
- ✔ Airbag warning light illuminated, often with DTC B1001.
- ✔ Unexplained battery drain while the vehicle is off.
- ✔ Communication errors with other vehicle modules, leading to various warning lights.

Installation and Post-Install Procedures
The BCM is typically located under the driver’s side dashboard, near the steering column, making physical replacement a quick job for most DIY mechanics. However, depending on your vehicle’s specific configuration, some post-installation steps may be necessary:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for my BCM?
It means we load the module with your truck’s specific software and factory settings using your Vehicle Identification Number (VIN). This makes the unit ready for installation right out of the box, with no need for dealership programming.
Is this part difficult to install myself?
The physical installation is straightforward, usually taking less than 15 minutes with basic tools. It’s located under the steering column. However, be aware that post-install electronic procedures, like an airbag system sync, may require a professional scan tool.
Do I need to return my old BCM?
No. This part is sold with no core charge, so you can keep your original module without any extra fees or hassle.
How can I be sure my BCM is the problem?
While the symptoms listed above are strong indicators, a proper diagnosis with a scan tool is the best way to confirm. Common BCM-related trouble codes and a multitude of electrical failures point to a faulty module.
Will this fix my airbag light with code B1001?
A faulty BCM can cause the B1001 code and illuminate the airbag light. Replacing it often resolves the issue, but you will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to sync the systems and turn off the light.
