Are you battling strange and frustrating electrical problems in your 2003-2007 GMC Sierra, Chevrolet Silverado, or other GM truck? A faulty Body Control Module (BCM) is often the culprit behind issues like malfunctioning lights, unresponsive power windows, erratic HVAC controls, or even a no-start condition. This OEM-quality Body Control Module, part number 15194170, is the definitive solution, arriving expertly programmed to your vehicle’s VIN for a true plug-and-play installation.
Is Your Truck Showing Signs of BCM Failure?
A failing BCM can disrupt your vehicle’s entire electrical system. Look out for these common symptoms that indicate it’s time for a replacement:
- ✔ Unresponsive or intermittently working power windows, door locks, or mirrors.
- ✔ HVAC blower motor not working or climate controls failing to respond.
- ✔ The security system light flashing, causing a no-start or crank-no-start condition.
- ✔ An illuminated airbag warning light, often with diagnostic trouble code (DTC) B1001.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ Wipers behaving erratically or not working when commanded.

Installation and Post-Install Notes
Installation is straightforward. The BCM is typically located under the driver’s side dash, near the steering column. Simply disconnect the battery, remove the old module, and plug this new one in. No core charge is required, so you can keep your old part. In some cases, additional steps may be needed:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool 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 operation.
Frequently Asked Questions
What does a Body Control Module do on a GMC Sierra?
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 lights, the security system, wipers, and HVAC controls.
Is this BCM ready to install out of the box?
Yes. We pre-program the module to your vehicle’s specific VIN before it ships. This makes the installation plug-and-play and means you do not need to visit a dealership for additional programming.
What if my airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key’ procedure to resolve this.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module without any extra fees or hassle.
Will this part fit a Chevrolet Silverado or a Cadillac Escalade?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Chevrolet Silverado, Suburban, Tahoe, Avalanche, Cadillac Escalade, and Hummer H2. Please verify the part number for your specific vehicle.
