Is Your GM Truck Plagued by Bizarre Electrical Issues?
Are random electrical gremlins turning your dependable Chevrolet Silverado, GMC Sierra, or Tahoe into a source of constant frustration? One minute the power windows work, the next they don’t. The HVAC blower quits on the hottest day of the year. A persistent airbag light stays on your dash, accompanied by confusing error codes. These aren’t separate problems—they’re classic symptoms of a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. Don’t let a faulty module compromise your truck’s safety and functionality. Restore order and reliability with this direct-fit, VIN-programmed GM 25844480 BCM.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and the latest GM software onto the module before we ship it. This ensures it communicates perfectly with your truck’s other computers (like the ECU and TCM) right out of the box, just like the original part did.
Is this a difficult part to install myself?
For most people, no. 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. No special tools are required for the installation itself.
My airbag light is on. Will this BCM fix it?
Yes, this module will resolve the communication fault that often causes the airbag light and code B1001. However, after installation, you may need to perform an ‘SDM Key Relearn’ or ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool to sync the new BCM with the airbag system and turn off the light.
Do I need to return my old BCM?
No. We do not require you to send back your original module. There is no core charge associated with this part, which simplifies your repair process.
How do I know if this is the right part for my vehicle?
This module replaces many part numbers, including 15263497, 25835966, and others listed. The best way to confirm is to check the part number on your original BCM or use the detailed fitment list on this page. If you’re still unsure, please contact us with your VIN, and we’ll be happy to verify compatibility for you.
