Are you dealing with a cascade of bizarre electrical issues in your GM truck or SUV? One moment the wipers won’t turn off, the next the power windows are dead, and a persistent airbag light is staring you down.

Expert Insight: The Critical Role of VIN Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used BCM from a salvage yard. This almost always leads to more problems. A BCM is not a simple relay; it’s a computer that’s coded specifically to the features and security system of the original vehicle it came from. Installing a non-programmed module can cause feature mismatches (like trying to control power-folding mirrors your truck doesn’t have) or, worse, a no-start condition due to a security system conflict. Our VIN Programmed GM 25844480 BCM completely bypasses this nightmare scenario. We handle the complex programming on our end, so you receive a part that communicates perfectly with your vehicle right out of the box.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, door locks, interior/exterior lighting, wipers, the security system, and the HVAC climate control system.
Why is VIN programming so important for this part?
VIN programming configures the BCM to the specific options and security protocols of your vehicle. Without it, the module won’t know how to operate your truck’s features correctly and may conflict with the anti-theft system, preventing the vehicle from starting. Our service ensures it’s a simple plug-and-play part.
How difficult is the installation?
Installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard, near the steering column. For most models, it’s a simple process of disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one. The entire process often takes less than 15 minutes.
My airbag light is on. Will this BCM fix it?
This module often resolves issues causing airbag DTC B1001. However, after installation, if the light remains on, a special procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool. This re-syncs the new BCM with the airbag system. This is a common final step for GM vehicles of this era.
Do I need to return my old BCM?
No. We do not require a core return for this part. You can keep or dispose of your old module at your convenience, simplifying the repair process for you.
Will this work for my 2010 Chevrolet Silverado 1500?
Yes, this VIN Programmed GM 25844480 BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the 2010 Silverado 1500. It serves as a direct replacement for numerous original part numbers to ensure a perfect fit and function.
