End the Electrical Headaches in Your GM Truck or SUV
Is your Silverado, Sierra, or Tahoe suffering from baffling electrical issues? One moment the A/C works, the next it doesn’t. Power windows have a mind of their own, and strange warning lights appear on the dash. These aren’t just annoyances; they’re symptoms of a failing Body Control Module (BCM), the central computer for your vehicle’s comfort and security features. This genuine GM 25844480 BCM, pre-programmed to your vehicle’s specific VIN, is the definitive solution to restore order and get your dependable truck back on the road, functioning exactly as it should.

- Intermittent or total loss of HVAC and climate controls.
- Power windows, door locks, or mirrors that work sporadically or not at all.
- An airbag warning light that won’t turn off, often with DTC B1001.
- Security system malfunctions, causing no-start conditions or random alarm triggers.
- Exterior or interior lights behaving erratically.
- A host of seemingly unrelated diagnostic trouble codes (DTCs).

From the Technician’s Bench: One of the biggest challenges with a failing BCM is the ‘ghost in the machine’ effect.

It eliminates the hours of diagnostic headaches and gets the truck back to being the reliable workhorse it was built to be.
Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we flash the module with your truck’s unique 17-digit Vehicle Identification Number (VIN) before we ship it. This loads all the specific software and settings for your vehicle’s options, making the installation a simple plug-and-play process without needing a dealer’s scan tool.
Is this difficult to install myself?
For most DIYers with basic tools, the installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes only a few minutes. However, please review the post-installation procedures, as some vehicles may require an additional step for the airbag system.
My airbag light is on. Will this fix it?
Yes, a faulty BCM is a common cause of the airbag light, especially with code B1001. After installing this new module, if the light remains on, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a capable scan tool to sync the new BCM with the airbag system. This is a common final step.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any extra fees or hassle.
How do I know if this is the right part for my truck?
This module fits a wide range of 2007-2013 GM trucks and SUVs. The best way to confirm is to match your original part number to one of the interchangeable numbers listed (e.g., 25844480, 20939137). If you’re unsure, please provide us with your VIN, and we will verify the fitment for you.
