Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical issues in your 2003-2007 GM vehicle? Flickering lights, unresponsive power windows, a malfunctioning security system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can cause a wide range of seemingly unrelated problems. This OEM-quality replacement BCM, part number 15194170, is the definitive solution to restore your vehicle’s performance and reliability.
Is Your Body Control Module Failing?
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:
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or flicker randomly.
- ✔ HVAC system problems, such as a blower motor that doesn’t work or climate controls that are inoperative.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code B1001.
- ✔ Security system malfunctions, including false alarms or no-start conditions where the engine won’t crank.
- ✔ Intermittent failure of windshield wipers or radio controls.
The Plug-and-Play Solution for Your 2003-2007 Sierra BCM
Replacing a BCM used to mean a mandatory trip to the dealership for expensive programming. Our modules eliminate that step. We pre-program this BCM to your vehicle’s specific VIN before shipping, ensuring it integrates seamlessly with your existing systems. This process loads the latest GM software and calibrations, providing optimal performance right out of the box. This is a direct replacement for a wide range of GM trucks and SUVs, including the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, Cadillac Escalade, and Hummer H2.
Installation and Post-Install Notes
Physical installation is straightforward and typically takes less than 15 minutes. The BCM is usually located under the driver’s side dashboard near the steering column. Simply disconnect the battery, remove the old module, plug in the new one, and reconnect the battery. While our VIN programming handles the primary setup, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. This syncs the new BCM with the airbag system. Additionally, a brake pedal position sensor relearn might be needed on certain models. Best of all, there is no core charge, so you can keep your old part without any hassle.
