Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, a malfunctioning climate control system, power windows with a mind of their own, or strange security system alerts on your GMC Yukon, Chevrolet Tahoe, or Silverado, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This genuine quality GM 25844480 BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
From the Diagnostic Bay
We had a 2009 Silverado 2500 in the shop that was driving the owner crazy. The radio would turn on by itself, the dome lights would stay on, and the battery would be dead every other morning. He had already replaced the battery and alternator. After checking all the usual suspects like grounds and wiring harnesses, we traced the parasitic draw back to the BCM. It was failing internally, keeping other modules awake even when the truck was off. Installing a VIN-programmed BCM like this one solved every single issue in under 10 minutes. It’s a common failure point that can mimic a dozen other problems.
Symptoms of a Failing 2007-2011 Yukon BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s time to consider a replacement:
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC and climate control systems not working correctly, or the blower motor functioning intermittently.
- ✔ The security system acting up, causing no-start conditions or random alarm triggers.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Intermittent stalling, misfires, or other performance issues related to poor data communication.
- ✔ Multiple communication-related DTCs stored in various modules.

Installation and Post-Install Notes
Installation is straightforward for any DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the negative battery terminal, unplug the electrical connectors from the old module, remove it, and install the new one. While the unit is plug-and-play, some vehicles may require a simple relearn procedure:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to use a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be needed to ensure correct brake light operation.
This is a new, OEM-quality part backed by a one-year warranty, and there is no core charge. You can keep your old part without any hassle.
Frequently Asked Questions
Is this Body Control Module truly plug-and-play?
Yes. We program the module using the VIN you provide during checkout. This ensures it has the correct software and configuration for your specific vehicle, eliminating the need for dealership programming.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep or dispose of your original module without any additional fees.
What if my airbag light is on after I install this BCM?
This is a normal security measure on some GM vehicles. The new BCM needs to be electronically ‘introduced’ to the airbag’s Sensing and Diagnostic Module (SDM). A repair shop with an advanced scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to resolve this.
How can I be sure the BCM is the cause of my problems?
The symptoms listed above are strong indicators of BCM failure. However, electrical issues can be complex. We recommend confirming the diagnosis with a professional scan tool that can check for communication errors with the BCM (U-codes) or specific BCM-related fault codes (B-codes).
Will this fit my 2010 Chevrolet Silverado?
Yes, this BCM fits a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade. It is a direct replacement for numerous part numbers. Please verify your vehicle in the fitment chart on this page.
