Tired of Electrical Gremlins in Your GM Truck?
If your 2003-2007 Chevrolet Silverado, GMC Sierra, or other compatible GM vehicle is suffering from bizarre electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your truck’s body electronics, managing everything from your power windows and door locks to your interior lights and HVAC system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems.
Is Your Truck Showing Signs of BCM Failure?
A faulty BCM can manifest in many ways. Here are the most common symptoms to watch for:
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working.
- ✔ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔ The security system acts up, causing a no-start condition or the alarm to go off randomly.
- ✔ An airbag warning light is illuminated on the dash, often with a B1001 DTC.
- ✔ Unexplained battery drain when the vehicle is off.

Installation & Post-Install Notes:
Installation is straightforward, typically taking less than 15 minutes. The BCM is usually located under the driver’s side dashboard, near the steering column. Simply disconnect the battery, swap the modules, and reconnect the battery. In some cases, additional steps may be needed:
- Airbag System Sync: If the airbag light appears after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control function.

Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the main computer for your truck’s non-engine related electronics. It controls features like power windows, locks, lights, wipers, the security system, and the HVAC fan.
Is this BCM difficult to install?
No, installation is very simple for most DIYers. It’s typically located under the steering column, held in by clips or a few bolts. The entire process of swapping the part usually takes less than 15 minutes.
Will I need to take my truck to the dealer after installing this?
No. This BCM comes pre-programmed to your vehicle’s VIN. This allows for a simple plug-and-play installation without the need for expensive dealership programming.
What happens if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a professional-grade scan tool.
How do I know this is the correct part for my truck?
Please verify that your vehicle’s year, make, and model are listed in the compatibility chart. Matching your original part number to one of the interchangeable numbers listed also ensures a perfect fit.
Is there a core charge for my old BCM?
No, there is no core charge. You can keep or dispose of your old module without the hassle of sending it back.
