Is Your 2010 Avalanche Experiencing Strange Electrical Issues?
If you’re dealing with flickering lights, power windows that have a mind of their own, a security system that won’t cooperate, or random warning lights on your dash, you’re likely facing a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and unpredictable problems. Don’t let electrical gremlins ruin your driving experience. This is the reliable, straightforward solution you need.
This listing is for a direct-fit replacement Body Control Module, part number 25826125, for your 2010 Chevrolet Avalanche and other compatible GM vehicles. To ensure a simple and successful installation, we program the module to your vehicle’s specific VIN before it ships. This critical step integrates the BCM with your truck’s existing systems, saving you a trip to the dealership and the high cost of programming fees.
Common Symptoms of a Failing 2010 Avalanche BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Instrument cluster gauges behaving erratically or displaying incorrect information.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Communication errors with other vehicle modules, often triggering multiple warning lights.
Installation and Post-Install Procedures
Installation is straightforward, but please be aware of potential post-installation steps. After installing the new BCM, certain systems may need to be re-synced. Specifically:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific guidance.
