Restore Full Control Over Your Vehicle’s Electronics

Are you battling frustrating electrical gremlins in your Chevrolet, GMC, or Cadillac? When power windows act on their own, the HVAC system quits, or warning lights appear for no reason, a failing Body Control Module (BCM) is often the culprit. This vital electronic hub manages dozens of functions that you rely on every day. Our programmed 25844480 BCM is the definitive, hassle-free solution to restore your vehicle’s functionality and your peace of mind. It arrives pre-configured to your vehicle’s specific VIN, eliminating the need for expensive dealership programming and getting you back on the road faster.

Common Symptoms & Your Solution

A faulty BCM can cause a wide range of confusing and intermittent issues. If you’re experiencing any of the following, this module is the solution you need:

  • Intermittent or complete loss of climate control (HVAC) functions.
  • Power windows, door locks, or exterior/interior lights not working correctly.
  • The security system malfunctioning, causing no-start or stalling conditions.
  • An airbag warning light on the dash, often with Diagnostic Trouble Code (DTC) B1001.
  • Unexplained battery drain or other persistent electrical problems.

By replacing your old unit with this pre-programmed 25844480 BCM, you directly address the root cause of these problems, restoring stable and reliable operation to all affected systems.

From the Expert’s Bench: Many people don’t realize that a BCM isn’t just a simple swap. An unprogrammed module from a salvage yard or a generic online seller won’t work correctly—it has to be coded specifically to your vehicle. We handle that critical step for you. By sending a programmed 25844480 BCM, we save you the time, towing costs, and high labor fees of a dealership visit. This is the smartest, most efficient way to solve complex electrical issues on these GM platforms.

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 power windows, door locks, interior and exterior lights, the security system, wipers, and the HVAC (climate control) system.

Is this BCM difficult to install?

Installation is typically very straightforward for someone with basic mechanical skills. The BCM is usually located under the driver’s side dashboard near the steering column. The physical swap often takes less than 15 minutes. Since our module is pre-programmed, no complex computer work is needed on your end.

Do I need to take my truck to the dealership after installation?

No. The main benefit of our service is that we program the module to your VIN before it ships. This means you can avoid a trip to the dealership for costly programming, making it a true plug-and-play solution.

What if my airbag light is still on after installing the new BCM?

In some cases, particularly if you had an airbag-related code like B1001, a final sync procedure is needed. This is called “Setup SDM Primary Key in BCM” and must be performed with a professional-grade scan tool. It’s a quick procedure for any competent repair shop but is not required for all vehicles.

Is there a core charge for my old part?

No, there is no core charge. You can keep your old module without the hassle of needing to return it.
