Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your vehicle? Flickering lights, unresponsive power windows, a malfunctioning security system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and seemingly unrelated issues. This genuine OEM-quality GM Body Control Module, part number 25844480, is the definitive solution for restoring order and reliability to your truck’s essential systems.
Is Your Sierra’s BCM Failing?
A faulty Body Control Module can manifest in numerous ways. If you’re experiencing any of the following symptoms, a failing BCM is the likely culprit:
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights behaving erratically (staying on, not turning on, flickering).
- ✔ HVAC climate control issues, including an inoperative blower fan or incorrect temperature blending.
- ✔ An illuminated airbag warning light, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Vehicle security system malfunctions, causing no-start conditions or false alarms.
- ✔ Wipers that won’t turn off or operate correctly.
- ✔ Communication errors with other vehicle modules, leading to a host of DTCs.
Why Choose Our Programmed 2013 Sierra Body Control Module?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The key benefit is our professional VIN programming service. We flash the module with your vehicle’s specific VIN and the latest GM software updates before it ships. This ensures that it communicates perfectly with your truck’s existing systems right out of the box. You get to skip the expensive trip to the dealership for programming, saving you time and money.
Installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes just a few minutes with basic tools. While the module is plug-and-play for most functions, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool if the airbag light remains on. This simple relearn syncs the new BCM with the airbag system. Additionally, a Brake Pedal Position Relearn might be needed to ensure proper brake light and stability control function.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lights, the security system, wipers, and the HVAC system.
Why is VIN programming so important for a BCM?
VIN programming loads your vehicle’s specific configuration and software into the module. Without it, the BCM won’t recognize your vehicle’s features, leading to system malfunctions or a complete failure to operate. Our pre-programming service makes the part truly plug-and-play.
Is this part difficult to install myself?
The physical installation is very simple for most DIY mechanics, typically taking less than 15 minutes. It involves removing a lower dash panel and swapping the module. However, post-installation procedures like an airbag system sync may require a professional scan tool.
What happens if my airbag light is on after installation?
If the airbag light is on, it means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure with a compatible high-end scan tool.
Do I need to return my old BCM?
No. This part is sold with no core charge, so you are not required to send your original module back to us.
