Restore Full Electrical Function to Your GMC Yukon
If you’re dealing with baffling electrical problems in your 2003-2006 GMC Yukon, a failing Body Control Module (BCM) is the likely culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from the power windows and door locks to the HVAC system and security features. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. This OEM-quality replacement BCM, part number 15137395, is the definitive solution to restore your truck’s reliability and functionality.
From the Diagnostic Bay
We had a 2005 Yukon come in with the strangest symptoms: the radio would stay on after the key was out, the driver’s side window wouldn’t go down, and the AC blower was dead. The owner had already replaced the battery and checked fuses. After hooking up our scanner, we saw multiple communication loss codes pointing to the BCM. Instead of a complex wiring chase, a new VIN-programmed BCM was the answer. We swapped it in 10 minutes, and every single issue was resolved instantly. It’s a common failure point that can look much more complicated than it really is.
Is Your Yukon Experiencing These BCM Failure Symptoms?
- ✔ Unresponsive power windows, door locks, or interior/exterior lights.
- ✔ HVAC system malfunctions, like a blower motor that won’t turn on or works erratically.
- ✔ An active airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Security system errors, causing no-start or intermittent starting conditions.
- ✔ A cluster of seemingly unrelated electrical issues that defy simple diagnosis.
Why Choose Our 2003-2006 Yukon Body Control Module?
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 using the latest official GM software updates. This critical step ensures that the BCM communicates flawlessly with your Yukon’s other electronic systems, like the engine computer and instrument cluster, right out of the box. You get a hassle-free installation that requires no expensive trip to the dealership for programming.
Post-Installation Guidance
While installation is plug-and-play, some vehicles may require minor post-installation procedures for full system synchronization. If the airbag warning light remains on, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional diagnostic tool. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary to ensure proper brake light and traction control operation. Always consult your vehicle’s service manual for specific instructions.
Frequently Asked Questions
What does ‘VIN Programmed’ mean for my Yukon?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software onto the module before shipping. This ensures it communicates perfectly with your Yukon’s other systems right out of the box, eliminating the need for expensive dealership programming.

Installation is straightforward for most DIYers. The BCM is typically located under the steering column. It involves disconnecting the battery, unplugging the old module, and plugging in the new one. The entire process usually takes less than 15 minutes.
Will this part fix my airbag light?
A faulty BCM can cause the airbag light to illuminate. While this replacement often resolves the issue, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to sync the new module with the airbag system 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 old module without any hassle or extra fees.
