Is Your 2010 Avalanche Experiencing Bizarre Electrical Problems?
If your Chevy Avalanche is acting possessed—with flickering lights, malfunctioning power windows or locks, or a security light that won’t turn off—a failing Body Control Module (BCM) is the likely culprit. The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; it can affect the security and drivability of your vehicle. Don’t let electrical gremlins take over. We offer a reliable, direct-fit solution to restore your truck’s functionality.
From the Diagnostic Bay
We recently had a 2010 GMC Yukon XL (which shares the same platform as the Avalanche) in the shop with a classic case of BCM failure. The owner reported that the radio would turn on and off by itself, the door locks would cycle while driving, and the instrument cluster would intermittently go dark. After ruling out battery and alternator issues, we traced the problem to a faulty BCM. Instead of a costly trip to the dealership for a new module and programming, we installed one of our VIN-programmed units. The installation was straightforward, and all the strange electrical issues were resolved immediately. The customer was back on the road the same day, saving significant time and money.
Symptoms of a Failing GM Body Control Module
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Instrument cluster lights flickering, gauges behaving oddly, or warning lights staying on (like the security or airbag light).
- ✔ The vehicle’s security system preventing the engine from starting.
- ✔ Interior or exterior lights not working correctly.
- ✔ Key fob failing to lock or unlock the doors.
- ✔ Communication errors with other vehicle modules, leading to various diagnostic trouble codes.

Post-Installation Information
While this module is designed for a straightforward installation, some vehicle systems may require a relearn procedure after the BCM is replaced. This is a normal part of the process.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and can be performed by any shop with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and stability control systems function as intended.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does the Body Control Module (BCM) do on my 2010 Avalanche?
The BCM acts as the main computer for your truck’s comfort and convenience features. It controls functions like the power windows, door locks, interior lighting, security system, and key fob operations.
Is this BCM ready to install out of the box?
Yes! This is a key benefit of our service. We program the BCM to your truck’s specific VIN before shipping, so it’s ready for installation without needing a trip to the dealer for programming.
How do I provide my VIN number?
You can add your 17-digit VIN to the notes section during checkout. If you forget, we will contact you via email after your purchase to request it. We cannot ship the module until it has been programmed.
Will this fix my ‘Service Airbag’ message?
If the message is caused by a faulty BCM, yes. However, after installing the new BCM, the airbag system will need to be synced using a professional scan tool to clear the light, as described in the post-installation procedures.
Do I have to send my old part back?
No. There is no core charge for this part. You can keep your original module.
