Are you experiencing frustrating electrical issues with your 2010 Chevrolet Avalanche? Problems like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are common signs of a failing Body Control Module (BCM). The BCM is the central computer for your truck’s body electronics, and when it fails, it can cause a wide range of unpredictable symptoms. This replacement Body Control Module is the reliable, straightforward solution to restore your vehicle’s full functionality.
We take the guesswork and high dealership costs out of the equation. Before we ship this module, we program it with the latest GM software updates specifically for your truck using the VIN you provide. This ensures a smoother installation process and optimal performance right out of the box. Simply provide your VIN after purchase, and we’ll handle the programming, getting you a part that’s ready to go.
From the Diagnostic Bay
We had a 2010 Tahoe (which uses the same BCM) come in with the weirdest collection of symptoms. The radio would turn off randomly, the driver’s side window wouldn’t go down, and the dome light would stay on, draining the battery. The owner had been to two other shops that couldn’t pinpoint the issue. We diagnosed a faulty BCM, and instead of a complicated dealer visit, we installed one of these pre-programmed units. The installation was simple, and all the bizarre electrical gremlins were gone instantly. It saved the customer hundreds in diagnostic fees and programming charges.
Common Symptoms of a Failing GM BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from the dashboard gauges or warning lights (including the security light).
- ✔ Headlights, taillights, or interior lights staying on or not turning on at all.
- ✔ The vehicle’s security system preventing the engine from starting.
- ✔ Problems with the heating and A/C blower motor controls.
- ✔ Remote keyless entry failure.

Important Post-Installation Information
While this module is programmed for your vehicle, some GM models may require a final synchronization step after installation. These procedures typically require a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn might be required.
Please consult a factory service manual or a qualified automotive technician if you are unsure about these final steps.
Frequently Asked Questions
What does the Body Control Module do on my 2010 Avalanche?
The BCM acts as the central hub for your truck’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and climate control features.
