Restore Your Truck’s Brain and End Electrical Frustrations
Are you battling a storm of strange electrical issues in your Chevrolet, GMC, or Cadillac truck or SUV? One moment the power windows work, the next they don’t. The HVAC controls have a mind of their own, and mysterious warning lights appear on your dash. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). This 25844480 Body Control Module is the definitive, plug-and-play solution, pre-programmed to your vehicle’s VIN to restore order and get your truck’s essential systems communicating perfectly again.
Common Symptoms & Your Solution
A faulty BCM can make your reliable workhorse feel unpredictable. If you’re experiencing any of the following, this module is the fix you need:
- Intermittent or completely dead HVAC and blower motor controls.
- An airbag warning light that won’t turn off, often with DTC B1001.
- Power windows, door locks, or interior/exterior lights that work sporadically or not at all.
- Security system malfunctions that may prevent the vehicle from starting.
- A cluster of confusing diagnostic trouble codes (DTCs) related to body electronics.
Instead of chasing down individual electrical gremlins, replacing the central BCM solves the problem at its source. Our 25844480 Body Control Module arrives ready for installation, saving you hundreds in dealership programming fees and diagnostic time.

Expert Insight: The Critical Role of VIN Programming
From our 20+ years of experience, the number one mistake people make when replacing a BCM is installing a used, un-programmed unit.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like your power windows, door locks, interior and exterior lighting, security system, wipers, and climate controls.
Is this module difficult to install?
Installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard near the steering column. For most owners, it’s a simple plug-and-play process that takes less than 15 minutes with basic tools.
Will I need to take my truck to the dealer after installation?
No. Because we pre-program the module to your vehicle’s VIN, you can skip the trip to the dealership. This part is designed to work immediately upon installation, saving you time and money on programming fees.
How do I know if my BCM is the problem?
A failing BCM typically causes multiple, seemingly unrelated electrical issues. If your power accessories, lights, and security system are all acting erratically, the BCM is the most likely culprit. A professional scan tool can also confirm the diagnosis by revealing communication-related DTCs.
What if the airbag light stays on after I install the new BCM?
In some cases, especially if you have an active airbag code like B1001, a post-installation procedure called “Setup SDM Primary Key in BCM” may be required. This can be performed with an advanced, bi-directional scan tool and syncs the new BCM with the airbag system.
Does this part have a core charge?
No, there is no core charge for this module. You can keep your old part without needing to send it back.
