Restore Full Functionality to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your Yukon, Silverado, or Tahoe? Flickering lights, a dead HVAC system, or power windows with a mind of their own are more than just an annoyanceโthey compromise your vehicle’s comfort and safety. The Body Control Module (BCM) is the central command for these systems, and when it fails, it can cause a cascade of confusing issues. This genuine GM 25844480 BCM, pre-programmed to your vehicle’s specific VIN, is the definitive solution to restore order and get your truck or SUV operating like new again.
Common Symptoms & Your Solution
A failing BCM can manifest in numerous ways, often leading to costly and incorrect diagnoses. If you’re experiencing any of the following, this module is your answer:
- Intermittent or complete loss of climate control (HVAC) functions.
- Power windows, door locks, or interior/exterior lights not working correctly.
- An airbag warning light on the dash, often with a DTC B1001 code.
- Erratic security system behavior, leading to no-start conditions or stalling.
- A variety of diagnostic trouble codes (DTCs) related to body electronics.
By replacing your old unit with this expertly prepared VIN programmed 25823559 BCM, you’re not just swapping a part; you’re installing a plug-and-play fix that communicates flawlessly with your vehicle’s other systems right out of the box.

Expert Insight: The Power of Proper Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners chase electrical problems for weeks, replacing batteries and alternators only to find the BCM was the culprit all along. The most critical step is the programming. An improperly programmed module can create more issues than it solves. That’s why we handle the VIN programming before we ship. It ensures the BCM correctly recognizes your vehicle’s specific optionsโfrom the type of radio to the security systemโfor a seamless integration that a generic, non-programmed part simply can’t offer.
Frequently Asked Questions
Will I need to take my vehicle to the dealership after installation?
No. This BCM is pre-programmed to your vehicle’s VIN, making it a true plug-and-play solution. In most cases, no further steps are required. However, if an airbag light persists, a special function on a high-end scan tool may be needed to sync the SDM key.
What tools are needed for installation?
Installation is typically very simple and requires basic hand tools, such as a socket set or a screwdriver, to remove the lower dash panel for access. The module itself is held in by clips or small bolts and has simple plug-in electrical connectors.
How do I know if this BCM is compatible with my vehicle?
This module fits a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade. The best way to confirm is to match the part number from your original BCM to one of the compatible numbers listed, such as 25823559. You can also use the fitment guide on our website.
What does “no core charge” mean?
A core charge is a deposit you pay until you return your old, faulty part. We do not have a core charge on this BCM, which means you can keep or dispose of your original module without the hassle of shipping it back to us.
My airbag light is on with code B1001. Will this fix it?
A faulty BCM is a very common cause of the B1001 code. Replacing it with this programmed unit should resolve the issue. After installation, if the light remains, you may need to perform the “Setup SDM Primary Key in BCM” procedure with a compatible professional scan tool to finalize the communication between the airbag system and the new BCM.
