Is your 2010 Chevy Tahoe suffering from strange and unpredictable electrical problems? A faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your power windows and locks to the interior lights and security system. When it fails, it can cause a cascade of frustrating issues that are difficult to diagnose.
This is a direct replacement Body Control Module, part number 20864768, for your 2010 Tahoe and a wide range of other GM vehicles. To make your repair as simple as possible, we program the module to your vehicle’s specific VIN before shipping. This ensures compatibility and proper function of your vehicle’s features, saving you a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest.
From the Diagnostic Bay
We had a 2010 Yukon XL (which uses the same BCM) come into the shop with the classic signs of BCM failure. The customer complained that the radio would stay on after shutting the truck off, the dome lights would flicker randomly, and the battery would be dead every few mornings. After confirming power and grounds were good, we diagnosed a faulty BCM causing a parasitic drain. Swapping in a pre-programmed module like this one resolved all the issues instantly. It’s a common failure, but thankfully, a straightforward fix with the right part.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Instrument cluster warning lights appearing randomly (like the airbag light).
- ✔ A persistent parasitic battery drain that kills your battery overnight.
- ✔ Communication errors with other modules when scanned with a diagnostic tool.

Please Note: While this module is programmed for your vehicle, some models may require a simple post-installation procedure.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors the various electronic accessories in the body of the car. This includes power windows, locks, lights, wipers, security systems, and more.
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 order until we receive this information.
Is this part difficult to install?
For a 2010 Tahoe, the BCM is typically located under the steering column. Installation involves disconnecting the battery, removing a few trim panels, and swapping the module. It is a manageable job for a DIYer with basic tools, but always consult a service manual for your specific vehicle.
Will this fix my specific electrical problem?
This module will correct issues directly caused by a faulty BCM. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the source of your problem before ordering.
What if my airbag light comes on after installation?
This is a known possibility. The new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
