Is Your 2010 Avalanche Experiencing Bizarre Electrical Problems?
If your truck’s power windows, door locks, interior lights, or security system are acting erratically, the cause is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a host of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; a faulty BCM can affect vehicle security and safety systems. Restore proper function and peace of mind with our direct-fit, VIN-programmed replacement BCM.
From the Diagnostic Bay
We had a 2010 Avalanche 1500 come into the shop with a classic case of electronic gremlins. The customer reported that the dome lights would stay on, the power locks would cycle randomly while driving, and the radio would sometimes refuse to turn off after opening the door. A scan tool showed multiple communication loss codes with various modules. After checking the main power and ground connections, we focused on the BCM. Swapping in a pre-programmed module like this one instantly solved all the issues. The customer was thrilled to have their truck back to normal without a costly and time-consuming trip to the dealership.
Diagnosing a Faulty 2010 Avalanche Body Control Module
A failing BCM can mimic other problems, but a few key symptoms point directly to this critical component. If you’re experiencing several of these issues simultaneously, there’s a high probability your BCM is the culprit.
Common Failure Symptoms:
- ✔ Intermittent or non-functional power windows, mirrors, or door locks.
- ✔ Erratic instrument cluster behavior, such as flickering gauges or warning lights.
- ✔ Security system faults or the alarm sounding for no reason.
- ✔ Interior or exterior lights not working correctly (staying on or not turning on).
- ✔ Remote Keyless Entry (RKE) system failure.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
- ✔ Issues with the heating and A/C blower motor controls.
A True Plug-and-Play Solution
Dealerships require you to purchase a new module, pay for installation, and then pay an additional fee for programming. We simplify the process. This module is not just a part; it’s a complete solution. When you order, simply provide us with your vehicle’s 17-digit VIN. Our technicians will program the module with the latest GM software specific to your 2010 Avalanche 1500. This ensures that the BCM works seamlessly with your truck’s existing options and systems right out of the box. While the module is plug-and-play, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which can be performed with a capable scan tool.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, locks, lights, security system, wipers, and more. It acts as a central hub for these electronic features.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to function in your truck.
Is this part difficult to install?
On the 2010 Avalanche, the BCM is typically located under the steering column. Installation involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. It is a manageable job for a DIYer with basic tools. However, always consult a service manual for your specific vehicle.
Will I need to have this programmed by a dealer?
No. This module comes fully programmed to your vehicle’s VIN with the latest GM software updates. This saves you a trip to the dealer. In some cases, a ‘Setup SDM Primary Key in BCM’ or ‘Brake Pedal Position Relearn’ may be needed if you see related warning lights after installation.
What if my original part number is not on the list?
The provided list covers a wide range of compatible part numbers. If your number is not listed, please contact us with your VIN and original part number before ordering to ensure we can provide a compatible solution for you.
Is there a core charge?
No, there is no core charge for this part. You can keep your original module.
