Expert Technician’s Tip: Before you condemn your old BCM, take a moment to check the main ground connections associated with it, typically located near the driver’s side kick panel.

Ensuring a clean, tight ground connection during installation is a simple step that can prevent major headaches and ensure a successful repair.

Frequently Asked Questions
What does a Body Control Module do on a Silverado 3500?
The BCM acts as the central computer for your truck’s non-engine related electronics. It controls functions like the power windows, door locks, interior and exterior lighting, security system, wipers, and the HVAC system, ensuring they all work together correctly.
Do I need to program this BCM?
No. This module is sold as a VIN-programmed unit. We program it with the latest GM software using your vehicle’s VIN before it ships, making it ready for a plug-and-play installation right out of the box. This completely bypasses the need for a dealership visit.
How do I know if my BCM is failing?
Common signs of a failing BCM include multiple, unrelated electrical issues happening at once. This can include flickering lights, non-working door locks or windows, security system alerts, or HVAC problems. Diagnostic trouble codes related to body systems are also a strong indicator.
Where is the BCM located on my 2013 Silverado 3500?
The 2013 Silverado 3500 Body Control Module is typically located inside the cabin, under the driver’s side of the dashboard, near the steering column. Installation usually takes less than 15 minutes with basic tools.
What happens if the airbag light is on after installation?
In some cases, particularly if you have an existing DTC like B1001, the airbag system (SDM) may need to be re-synced with the new BCM. This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed with a professional-grade scan tool.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep your old module without any hassle or need to return it.
