Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2003-2006 GMC Yukon XL 2500, Chevrolet Silverado, or another compatible GM vehicle? Symptoms like flickering lights, a malfunctioning HVAC system, erratic power windows and locks, or a persistent airbag light often point to a single culprit: a failing Body Control Module (BCM). This genuine GM 15116066 BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation that gets you back on the road without a costly trip to the dealership.
Common Symptoms of a Failing GM BCM
If you’re experiencing any of the following issues, a faulty BCM is the likely cause. Replacing it can resolve multiple problems at once.
- ✔ Unresponsive or intermittent power windows, door locks, or interior lights.
- ✔ HVAC blower motor not working or climate controls failing to respond.
- ✔ Airbag warning light is illuminated, often with a B1001 diagnostic trouble code.
- ✔ Vehicle security system malfunctions, leading to no-start or anti-theft light issues.
- ✔ Parasitic battery drain causing a dead battery after the vehicle sits.
- ✔ Wipers behaving erratically or not working at all.
Why Choose Our Programmed Yukon XL 2500 BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We handle the complex programming so you don’t have to. Using the latest GM software updates, we flash the module with your vehicle’s VIN, ensuring it communicates perfectly with the other computers in your truck, like the ECU and instrument cluster. This process restores factory functionality and resolves common communication-based DTCs. Built to strict OEM standards and backed by a one-year warranty, this module provides a reliable, long-term repair for your vehicle’s electrical system.
Installation and Post-Install Notes
Installation is simple for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Always disconnect the battery before swapping modules. In most cases, the vehicle will start and run perfectly after installation. However, for some models, a couple of post-install procedures may be needed:
- Airbag System Sync: If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some vehicles may require this relearn procedure to ensure proper brake light and traction control operation.
Frequently Asked Questions
What does a BCM do on my 2004 GMC Sierra or Chevy Tahoe?
The Body Control Module acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows, door locks, security system, wipers, and HVAC system.
Is this 15116066 BCM really plug-and-play?
Yes! Because we pre-program the module to your vehicle’s VIN before shipping, it eliminates the need for dealer programming. You can install it yourself and, in most cases, it will work immediately.
What if my airbag light is still on after installation?
This is a common security feature. You will need a technician with a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new module with your airbag system.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module without any hassle or extra fees.
