Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your Chevrolet Silverado, GMC Sierra, or Tahoe? Flickering lights, unresponsive power windows, a dead HVAC blower, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and disruptive issues. This genuine quality GM Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a straightforward, plug-and-play installation.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights failing to turn on or off correctly.
- ✔ HVAC and climate control functions are unresponsive or intermittent.
- ✔ The security system is malfunctioning, causing no-start conditions or false alarms.
- ✔ An airbag warning light is illuminated on the dash, often with DTC B1001.
- ✔ Wipers are behaving unpredictably or not working at all.
- ✔ Multiple diagnostic trouble codes (DTCs) related to body systems are stored.
The Plug-and-Play Solution: Your Pre-Programmed GM Body Control Module
Forget about expensive dealership visits and additional programming fees. We take the hassle out of the repair by programming this module to your vehicle’s specific VIN before it ships. This ensures that all factory settings and operational parameters are perfectly matched to your truck or SUV right out of the box. The module is loaded with the latest GM software updates to provide optimal performance and reliability. By controlling all critical body functions, this BCM restores smooth operation and eliminates the diagnostic headaches associated with a faulty unit.
Installation is simple: The BCM is typically located under the driver’s side dash, near the steering column. In most cases, the replacement takes just a few minutes. However, please note that if your vehicle has an active airbag light due to the old BCM, a post-installation procedure called ‘Setup SDM Primary Key in BCM’ will be required using a professional-grade scan tool to sync the new module with the airbag system. A brake pedal position relearn may also be necessary on some models.

Frequently Asked Questions
What does a Body Control Module do on my Silverado or Sierra?
The BCM acts as the main computer for your truck’s non-engine related electronics. It controls functions like your power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC blower motor.
Is this BCM really plug-and-play?
Yes, it is. We pre-program the module to your vehicle’s VIN before shipping, so it’s ready for installation without needing a trip to the dealership for additional programming.
My airbag light is on after installing the new BCM. What do I do?
This is a common security measure. You will need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system (SDM) and will turn off the light.
Where is the BCM located on my 2009 Tahoe?
On most 2007-2013 GM trucks and SUVs, including the Tahoe, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
Do I need to return my old part?
No, there is no core charge for this part. You can keep or dispose of your old module without any hassle.
Will this fix my intermittent HVAC blower?
A faulty BCM is a very common cause of intermittent or non-functional HVAC blower motors and climate controls. If the blower motor resistor has already been checked, the BCM is the next logical component to inspect and replace.
