Restore Full Electrical Function to Your GM Truck or SUV
Is your 2007-2011 Chevrolet Tahoe or other GM vehicle plagued by baffling electrical issues? One moment the power windows work, the next they don’t. The security light flashes randomly, or the HVAC system has a mind of its own. These are classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s comfort and convenience features. This genuine GM BCM, part number 25844480, is the definitive, hassle-free solution. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2009 Silverado in the shop that was driving its owner crazy. The radio would turn off, the door locks would cycle while driving, and the AC blower was intermittent. The owner had already replaced the blower motor resistor and the master window switch with no luck. After hooking up our scanner, we saw a dozen communication codes all pointing back to one source. A faulty BCM was corrupting the data network. We installed a VIN-programmed module like this one, and in under 10 minutes, every single electrical gremlin was gone. It’s a reminder that when multiple, unrelated electronics fail at once, the BCM should be the first suspect.
Is Your Vehicle Showing These BCM Failure Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, dome lights) staying on or not turning on.
- ✔ HVAC controls are unresponsive, or the blower motor works intermittently.
- ✔ The anti-theft or security system light is illuminated, potentially causing no-start conditions.
- ✔ The windshield wipers behave unpredictably, activating on their own or not working when commanded.
- ✔ An airbag warning light is on, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Multiple communication error codes stored in various modules.

Installation and Post-Install Considerations
Physically installing the BCM is straightforward. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped out in minutes with basic hand tools. However, after installation, some vehicles may require additional electronic procedures for full system integration.
- Airbag System Sync: If the airbag warning light remains on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool and syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to satisfy the traction control system.
There is no core charge for this part, so you can keep your old module without the hassle of returning it. By choosing this pre-programmed 2007-2011 Tahoe BCM, you are getting a reliable, long-term fix that restores your vehicle’s complex electronic systems to their original state.
Frequently Asked Questions
What does the Body Control Module do on a 2007-2011 Tahoe?
