Restore Full Electrical Function to Your GMC Yukon XL 2500
Are you battling frustrating electrical gremlins in your 2003-2006 GMC Yukon XL 2500? Issues like flickering lights, unresponsive power windows, a malfunctioning security system, or erratic HVAC controls often point to a single culprit: a failing Body Control Module (BCM). This essential component acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a wide range of confusing and intermittent problems. This OEM-quality replacement BCM, part number 15194170, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play installation.
Common Symptoms of a Failing Yukon XL 2500 BCM
- ✔ Unresponsive or intermittently working power windows, door locks, or interior lights.
- ✔ HVAC system failures, such as the blower motor not working or temperature controls being erratic.
- ✔ The security system acting up, causing no-start conditions or the alarm to go off randomly.
- ✔ An airbag warning light on the dash, often accompanied by diagnostic trouble code B1001.
- ✔ Wipers that won’t turn off or operate at the correct speed.
- ✔ A cluster of seemingly unrelated electrical issues that mechanics can’t trace to a specific fuse or wire.
Plug-and-Play Solution: No Dealership Visit Required
The biggest hurdle in replacing a BCM is the need for expensive dealership programming. We eliminate that step entirely. Simply provide your vehicle’s VIN during checkout, and we will program the module with the latest GM software updates specific to your Yukon. This ensures that all vehicle options are recognized and that the module communicates perfectly with the rest of your vehicle’s systems right out of the box. This is not just a convenience; it’s essential for restoring correct and reliable operation.
Installation and Post-Install Notes
Physical installation is simple for any DIYer. The BCM is typically located under the steering column. Disconnect the vehicle’s battery, swap the old module with your new one, and reconnect the battery. In most cases, the job is done. However, be aware of two potential post-installation procedures:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.

Frequently Asked Questions
What does the Body Control Module (BCM) do on my Yukon?
The BCM controls most of the non-engine related electronics in your vehicle, including the power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC blower controls.
