- Inaccurate gauge readings or warning lights on the instrument cluster.
- Erratic radio or climate control behavior.

Expert Insight: From the Shop Floor
As a technician, I’ve seen firsthand how a faulty BCM can sideline a perfectly good work truck. One customer came in with a 2005 Silverado 2500 where the dome lights would stay on, draining the battery overnight. After hours of chasing wires, we traced it to the BCM. A pre-programmed module like this one is the most efficient fix. It turns a complex, multi-day diagnostic headache into a simple component swap, getting you back on the jobsite or the road without costly delays. This is the smart, effective repair for a Programmed 2003-2007 Silverado Sierra BCM 15747545.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your VIN when you place your order, and the module will arrive ready to install and function correctly in your vehicle.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls many of the electronic accessories and features, such as power windows, door locks, interior and exterior lighting, the security system, and more.
Is this a difficult part to install?
The BCM is typically located under the steering column on trucks or in the center dash on vans. Installation is generally straightforward for someone with basic mechanical skills, involving disconnecting the battery and swapping electrical connectors. However, we always recommend consulting a factory service manual for your specific model.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any automotive shop with a professional-grade diagnostic scan tool. It is only required if the airbag light is illuminated after the swap.
How do I know if this part number fits my vehicle?
This module replaces several original part numbers, including 15167329, 15194169, 15747545, and more. Please check the detailed fitment list on this page.
