Restore Full Electrical Function to Your GM Truck or SUV
Are you dealing with baffling electrical issues in your 2003-2007 GMC Sierra, Chevy Silverado, or other GM vehicle? Flickering lights, unresponsive power windows, a malfunctioning security system, or a dead HVAC blower are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it fails, it can create a host of frustrating and seemingly unrelated problems. This OEM-quality replacement BCM, part number 15064149, is the definitive solution to restore your vehicle’s functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or stays stuck on one speed.
- ✔ An active airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions, including random alarm activation or a no-start condition due to PassLock issues.
- ✔ Strange instrument cluster behavior or warning lights that have no apparent cause.
- ✔ Communication errors between various electronic modules within the vehicle.
Why Choose Our Sierra 1500 Body Control Module?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the BCM communicates perfectly with your truck’s existing components right out of the box. You get to skip the expensive trip to the dealership for programming, saving you both time and money. Simply plug it in, and you’re ready to go.
Installation is straightforward, typically taking less than 15 minutes. The BCM is located under the driver’s side dashboard, near the steering column. For a smooth installation, we recommend disconnecting the vehicle’s battery before swapping the modules. While most functions will work immediately, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. This part is a direct replacement for multiple part numbers, including 15116066, 15136225, 15198116, and 15064149.
Frequently Asked Questions
What does this Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows and locks, wipers, HVAC system, and security features.
Will I need to get this module programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes the installation plug-and-play and saves you a costly trip to the dealership.
