Are you battling frustrating electrical problems in your GMC Yukon XL 2500? Issues like flickering lights, malfunctioning power windows, a dead HVAC system, or a persistent security light are classic signs of a failing Body Control Module (BCM). The BCM is the central command for your truck’s body electronics, and when it fails, it can create a cascade of confusing and seemingly unrelated problems. This OEM-quality replacement BCM, part number 15136877, is the definitive solution to restore your vehicle’s full functionality and peace of mind.
Common Symptoms of a Failing Yukon BCM
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security system acts erratically, causing a no-start condition.
- ✔ An airbag warning light on the dash, often with a B1001 diagnostic trouble code.
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
- ✔ Wipers or exterior lighting behaving unpredictably.

This ensures that all factory-installed options work correctly right out of the box. This module is a direct replacement for a wide range of part numbers, including 15116066, 15136225, 15136877, and more, making it the perfect fit for your 2003-2006 Yukon XL 2500.
Installation & Post-Install Notes:
Installation is simple, typically taking less than 15 minutes. The BCM is located under the driver’s side of the dashboard. Always disconnect the battery before swapping the module. While our programming handles the majority of the setup, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. Additionally, a Brake Pedal Position relearn may be needed. Best of all, there is no core charge—you can keep your old part.
Frequently Asked Questions
What does the Body Control Module do on my Yukon?
The BCM acts as the central computer for your truck’s body electronics. It controls non-engine related functions like power windows, locks, interior and exterior lighting, security system, wipers, and the HVAC system.
