Frequently Asked Questions
What does a BCM do on a 2003-2006 GMC Yukon?
The Body Control Module (BCM) is a computer that manages and controls many of your Yukon’s non-engine related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, these systems can become erratic or stop working altogether.
Is this BCM difficult to install?
No, the installation is typically very simple. The BCM is usually located under the driver’s side dashboard, near the steering column. It involves disconnecting the negative battery terminal and then unplugging a few color-coded electrical connectors to swap the modules. Most people can complete the job in under 5 minutes with basic tools.
Do I need to program this module after I receive it?
Absolutely not. We handle the programming for you before it ships. We use your vehicle’s VIN to load the correct software and settings, so it’s ready for immediate plug-and-play installation. This saves you from a mandatory and costly trip to a dealership or specialized shop.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s Supplemental Deployment Module (SDM). If the airbag light appears after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade scan tool to clear the light. This is a simple sync procedure, not a full reprogramming.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old, faulty BCM back to us, saving you time and shipping costs.
How do I know this 2003-2006 GMC Yukon BCM 15136225 will fit my vehicle?
This module fits a wide range of 2003-2007 GM trucks and SUVs. The best way to ensure compatibility is to match your original part number to one of the many interchangeable numbers listed in the description. Providing your VIN at checkout allows us to program it perfectly for your specific model and options.
