Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the central computer for your truck’s non-engine related electronics. It controls functions like power windows, power door locks, the security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Is this BCM difficult to install?
No, installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard, near the steering column. It’s a matter of disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one. The entire process often takes less than 15 minutes.
Do I need to get this module programmed by a dealer?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s VIN *before* we ship it. This makes it a true plug-and-play part, saving you the time, hassle, and significant expense of dealership programming.
What if my airbag light is still on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed with a professional-grade scan tool. It is only necessary if the airbag light appears after the new BCM is installed.
Will this 2003-2007 Silverado 2500 Body Control Module fix my specific electrical problem?
This module is the solution for the vast majority of issues listed in the description, such as failing lights, locks, windows, and HVAC controls. If you’re experiencing these symptoms, a failing BCM is the most common cause. It is the central hub for all those functions.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old BCM back to us, which saves you the cost and hassle of return shipping.
