Fix Persistent Electrical Problems in Your GM Truck or SUV
Are you dealing with baffling electrical issues in your truck? Intermittent wipers, flickering lights, a malfunctioning security system, or power windows with a mind of their own are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a wide range of frustrating and seemingly unrelated problems. This OEM-quality replacement BCM, part number 10367690, is the definitive solution for your 2003-2007 GM vehicle, including the Chevrolet Silverado, GMC Sierra, Tahoe, and Suburban.
Symptoms of a Failing Silverado 3500 Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Inoperative or erratic power windows, door locks, or mirrors.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security or anti-theft system prevents the vehicle from starting.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ An active airbag warning light, often accompanied by DTC B1001.
- ✔ False warnings on the instrument cluster display.
- ✔ Communication errors with other vehicle modules.
Plug-and-Play Solution with VIN Programming
Don’t waste time and money at the dealership. We pre-program this module to your vehicle’s specific VIN before shipping. This ensures that it works seamlessly with your existing keys, security system, and factory options right out of the box. The programming uses the latest GM software updates to guarantee optimal performance and reliability. This is a true plug-and-play repair that restores full functionality without needing an expensive trip for dealer calibration.
Installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the battery, un-plug the electrical connectors from the old module, remove it, and install the new one. While most installations are seamless, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. There is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does the Body Control Module do on my Silverado?
The BCM acts as the central computer for your truck’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, wipers, the security system, and HVAC controls.
Is this part ready to install when I receive it?
Yes! This BCM comes fully programmed to your vehicle’s VIN. This allows for a simple plug-and-play installation without requiring any additional programming from a dealership, saving you time and money.
Where is the BCM located?
On most 2003-2007 GM trucks and SUVs like the Silverado, Sierra, and Tahoe, the BCM is located under the driver’s side of the dashboard, typically attached to a bracket near the steering column.
Will this fix my airbag warning light?
A faulty BCM is a common cause of an airbag light with DTC B1001. Replacing it often resolves the issue. However, in some cases, a post-installation procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a capable scan tool to sync the new BCM with the airbag system.
