End Frustrating Electrical Problems in Your GMC Yukon
Are you dealing with baffling electrical issues in your 2003-2006 GMC Yukon? Flickering lights, a dead instrument cluster, power windows with a mind of their own, or an HVAC system that won’t cooperate are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and intermittent problems. This replacement Body Control Module, part number 10367690, is the definitive solution to restore your truck’s functionality and your peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program each module to your vehicle’s specific VIN, ensuring it communicates flawlessly with all other systems right out of the box. This eliminates the need for an expensive trip to the dealership for programming, saving you both time and money. Get your Yukon back to operating the way it was meant to, with reliable control over all its essential comfort and safety features.
Case Study: A Tricky Diagnosis
I had a 2005 Yukon Denali in my bay last month with a laundry list of complaints from the owner. The radio would randomly turn off, the driver’s side power lock was dead, and the airbag light was on. The owner had already replaced the battery and checked all the fuses. A scan showed a B1001 DTC (Option Configuration Error) and a loss of communication code. After verifying the main power and ground connections to the BCM were solid, it was clear the module itself was the culprit. These internal failures are common; over the years, I’ve seen hundreds of these GMT800 platform BCMs fail due to cracked solder joints on the circuit board. Installing a VIN-programmed BCM like this one resolved all issues in under 10 minutes, including the persistent airbag light.
Is Your Yukon Exhibiting These Electrical Faults?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs replacement:
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ HVAC controls not working or blower motor staying on constantly.
- ✔ The security system acting erratically, leading to a no-start condition.
- ✔ An illuminated airbag warning light, often with a DTC like B1001.
- ✔ Unpredictable behavior from your windshield wipers or radio.
- ✔ Diagnostic trouble codes related to loss of communication with other modules.
Your 5-Minute Path to a Fully Functional Yukon
Installation is a straightforward process that most DIYers can complete with basic tools. The key is our VIN programming, which makes this a true plug-and-play repair.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s systems.
- Locate the BCM: On most 2003-2006 Yukon models, the Body Control Module is located under the driver’s side of the dashboard, to the left of the steering column. It’s a black box with several multi-pin connectors.
- Swap the Module: Carefully unplug the electrical connectors from your old BCM. They have release tabs that need to be pressed. Once disconnected, unbolt or unclip the old module and remove it. Install the new module in its place and securely reconnect all the wiring harnesses.
- Final Steps: Reconnect your battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC. In most cases, the repair is complete. However, if your airbag light remains on, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key’ procedure.

Frequently Asked Questions
Do I need to send my old BCM back?
No. There is absolutely no core charge for this part. You can keep your old module, which saves you the hassle and cost of return shipping.
Is this part really plug-and-play?
Yes. We program the module to the VIN you provide during checkout. This ensures it has the correct software and configuration for your specific vehicle options, allowing for a simple installation without requiring a trip to the dealer.
What if my airbag light stays on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This is a security procedure called ‘Setup SDM Primary Key in BCM’ and requires a professional-grade bidirectional scan tool. This is only necessary if the light remains on after the swap.
What does the Body Control Module actually do?
The BCM acts as a traffic cop for your vehicle’s body electronics. It takes input from switches (like your window or headlight switch) and sensors, and then sends commands to operate those components. It controls a wide range of features, including power locks, windows, interior/exterior lighting, security system, wipers, and the HVAC system.
Will this fix a no-start problem?
It can. A faulty BCM can cause issues with the Passlock security system on these GM vehicles, which will prevent the engine from starting as an anti-theft measure. If your BCM is the source of the security fault, replacing it will resolve the no-start condition.
