Is your 2010 GMC Yukon or other compatible GM vehicle suffering from bizarre electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or a no-start condition often point to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating symptoms. This replacement Body Control Module, part number 20839063, is the reliable, cost-effective solution to restore your vehicle’s functionality.
Unlike a standard part from a dealership, this BCM comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN after purchase, and our technicians will flash the module with the latest GM software updates for your exact vehicle configuration. This means no expensive trip to the dealer for programming—saving you time and money.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is illuminated, preventing the engine from starting.
- ✔ The key fob is unresponsive or works intermittently.
- ✔ False warnings on the instrument cluster, such as “Service StabiliTrak” or “Service Airbag.”
- ✔ The engine cranks but will not start, or will not crank at all.
- ✔ Radio or climate control systems malfunctioning.

Post-Installation Procedures
While this module is programmed for your vehicle, some systems may require a simple relearn procedure after installation to sync correctly. These can often be performed with a high-end scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration may be necessary.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
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, such as power windows, locks, lights, security systems, and climate controls. It acts as the central hub for these electronic features.
Do I need to have this module programmed?
No. We program the module for you before it ships. You must provide your vehicle’s 17-digit VIN during or after checkout so we can load the correct software and settings for your specific vehicle.
Is this a simple plug-and-play installation?
For the most part, yes. You disconnect the battery, remove the old BCM, and install the new one. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake position sensor to function correctly.
What happens if I don’t provide my VIN?
We cannot ship your order without a VIN. The programming is essential for the module to work with your vehicle. We will contact you for the VIN, but this will delay your shipment.
Will this fix my specific electrical problem?
This module is the solution for a wide range of electrical issues. If your vehicle is experiencing several of the symptoms listed, a faulty BCM is the most likely cause. However, we always recommend proper diagnosis to confirm the BCM is the point of failure.
