Put an End to Frustrating Electrical Problems in Your GM Truck
Is your GMC Sierra, Chevy Silverado, or Tahoe acting possessed? When lights flicker, power windows refuse to work, and the HVAC system has a mind of its own, the root cause is often a failing Body Control Module (BCM). Your hard-working truck demands reliability, and these unpredictable electrical gremlins can bring your day to a halt. This genuine GM 25844480 BCM is the definitive solution, arriving fully programmed to your vehicle’s specific VIN for a true plug-and-play installation that gets you back on the road with confidence.
Common Symptoms & Your Solution
A faulty BCM can create a cascade of confusing issues. If you’re experiencing any of the following, this module is the fix you need:
- Intermittent or total loss of HVAC blower and climate controls.
- Power windows, door locks, or mirrors that work sporadically or not at all.
- Interior or exterior lights failing to turn on or off correctly.
- An airbag warning light that won’t go away, often with DTC B1001.
- Erratic security system behavior, causing no-start conditions or stalling.
- A dashboard lit up with various diagnostic trouble codes (DTCs) related to body electronics.

Expert Insight: The Heart of Your Vehicle’s Electronics
As a technician, I’ve seen countless hours and dollars wasted chasing electrical ghosts. A customer might replace a window motor, then a switch, and then a wiring harness, only to find the problem persists. The BCM is the ‘brain’ for all these components. When it starts to fail, it sends corrupt signals, making perfectly good parts appear faulty. Installing a properly programmed BCM is often the first and only step needed to fix a dozen problems at once. This 2013 Sierra 2500 programmed BCM is the most efficient path to restoring your truck’s dependability.
Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means the module arrives ready for installation right out of the box. We load your vehicle’s specific Vehicle Identification Number (VIN) and all related factory software onto the BCM before shipping. This ensures it communicates perfectly with your truck’s other computers, saving you a mandatory and costly programming session at a dealership.
How do I know if my BCM is the problem?
The most common indicator of a failing BCM is having multiple, unrelated electrical issues occurring at the same time. For example, if your radio, power locks, and interior lights are all acting up, the BCM is the most likely culprit, as it controls all of those functions. A professional scan tool can also pull specific BCM-related trouble codes.
Is this a difficult part to install?
For most DIYers with basic tools, this is a straightforward job. The BCM is typically located under the driver’s side dashboard, near the steering column. It’s usually held in by a few bolts or clips and has several large electrical connectors. The entire process often takes less than 30 minutes.
What if my airbag light stays on after installation?
In some cases, particularly if you had an airbag code like B1001, the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). This is a simple ‘Setup SDM Primary Key in BCM’ procedure that can be performed with a professional-grade scan tool. This syncs the modules and turns off the light.
Do I need to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this part, making the process faster and more convenient for you.
