Restore Your Truck’s Brain and End Electrical Chaos
Are you battling a frustrating list of electrical gremlins in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? One moment the power windows work, the next they don’t. The HVAC blower quits randomly, and mysterious warning lights appear on your dash. These aren’t separate problems—they’re classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. This replacement BCM, a direct fit for part number 25790508, arrives fully programmed to your vehicle’s VIN, offering a permanent, hassle-free solution to restore full functionality and peace of mind.
Common Symptoms & Your Solution
A faulty BCM can make your reliable truck or SUV feel unpredictable and unsafe. If you’re experiencing any of the following, this module is the definitive fix:
- Intermittent or non-working power windows, door locks, or interior/exterior lights.
- HVAC controls that are unresponsive or a blower motor that works sporadically.
- An airbag warning light that won’t turn off, often with DTC B1001 stored.
- Security system malfunctions that may prevent the vehicle from starting.
- A host of seemingly unrelated diagnostic trouble codes related to body systems.
Instead of chasing down individual electrical issues, address the root cause. Installing this Programmed 25790508 Body Control Module is the most efficient way to get all systems communicating and operating as the factory intended.

Expert Insight from Our Technicians
“Before you condemn your BCM, take a moment to check the main ground connections, especially the one located on the driver’s side A-pillar near the emergency brake pedal. These GM platforms are notorious for poor grounds causing bizarre electrical issues that mimic a bad BCM. A quick cleaning and tightening of this ground can sometimes solve the problem. If the issues persist after checking the ground, you can be confident that replacing the Programmed 25790508 Body Control Module is the correct next step to a permanent repair.”
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It reads inputs from switches (like your window or headlight switch) and sensors, and then sends commands to operate things like your lights, power locks, windows, wipers, security system, and HVAC fan speeds.
Why is providing my VIN so important?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for your specific model, year, and factory-installed options (like power seats, sunroof, etc.). This makes the installation truly plug-and-play and avoids conflicts that would otherwise require dealer-level tools to resolve.
Is this part difficult to install myself?
For most DIYers with basic tools, this is a very straightforward installation. The BCM is typically located under the driver’s side dashboard, near the steering column. It’s held in by a few clips or bolts and has several electrical connectors. The physical swap usually takes less than 15 minutes.
What if the airbag light is still on after I install it?
This is a known security feature on GM vehicles. If the airbag light remains on (often with code B1001), you will need a professional-grade scan tool to perform a simple function called “Setup SDM Primary Key in BCM” or “Airbag System Sync.” This one-time procedure syncs the new BCM with the airbag system and will turn off the light.
Will this fix my specific electrical problem?
This Programmed 25790508 Body Control Module is designed to fix the wide range of symptoms listed above. If your vehicle is experiencing multiple, intermittent electrical failures across different systems (windows, locks, lights, HVAC), a failing BCM is the most likely culprit.
Do I need to send my old BCM back?
No. There is no core charge or requirement to return your original part. You can keep it or dispose of it at your convenience, making the process faster and simpler for you.
