Is Your 2010 GMC Yukon Experiencing Strange Electrical Issues?
If your power windows are acting up, your interior lights are flickering, or you’re seeing random warning messages on your dash, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central nervous system for your Yukon’s body electronics, managing everything from the door locks and security system to the climate control and lighting. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems that can be difficult to diagnose.
From the Diagnostic Bay
We had a 2010 Yukon XL come into the shop with a complaint that would drive anyone crazy. The owner said that intermittently, the radio would shut off, the dome lights would flash, and the power locks would cycle on their own while driving. He’d already replaced the battery and checked the main grounds. After hooking up our diagnostic scanner, we saw multiple communication loss codes with various modules. Instead of a complex wiring nightmare, the root cause was a classic BCM failure. The internal processor was failing, sending corrupt data across the vehicle’s network. Installing a VIN-programmed BCM like this one resolved all the issues in under an hour. It’s a fix that restores not just the vehicle’s function, but the owner’s peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The anti-theft or security system acting up, preventing the vehicle from starting.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
- ✔ Intermittent issues with the radio or infotainment system.
- ✔ A parasitic battery drain that kills your battery overnight.
The Plug-and-Play Solution for Your 2010 Yukon Body Control Module
Don’t let a faulty BCM keep your truck off the road or force you into an expensive trip to the dealership. This replacement Body Control Module, part number 20935349, is the definitive solution. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the BCM communicates perfectly with your Yukon’s other computers, like the Engine Control Module (ECM) and Transmission Control Module (TCM), right out of the box. You get the latest GM software updates loaded, ensuring optimal performance and reliability.
Installation and Post-Install Considerations
Replacing the BCM is a straightforward process for a seasoned DIYer or any professional technician. It is typically located under the steering column on the driver’s side. After swapping the hardware, some vehicles may require additional steps to ensure all systems are fully operational.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is because the new BCM needs to be synchronized with the vehicle’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light operation and to keep the traction control system functioning as designed.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What does a Body Control Module do on my 2010 Yukon?
The BCM is a computer that controls and monitors the majority of your vehicle’s non-engine-related electronic functions. This includes power windows, locks, seats, lights, wipers, security system, and climate control. It’s the command center for passenger comfort and convenience features.
Is this BCM ready to install out of the box?
Yes! This is the key benefit of our service. We program the module with the latest GM software using the VIN you provide. This makes the installation process as close to plug-and-play as possible, saving you from needing specialized dealer tools for initial programming.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
What happens if my airbag light comes on after installation?
If the airbag light is on, it means the new BCM needs to be electronically ‘introduced’ to the airbag system computer (SDM). A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module without any additional fees or hassle.
