Restore Full Electrical Function to Your GM Truck or SUV
Are you battling bizarre electrical gremlins in your 2003-2007 GM truck or SUV? One moment your power windows work, the next they’re dead. Your HVAC controls have a mind of their own, and strange warning lights appear on the dash. These are classic signs of a failing Body Control Module (BCM), the central computer for your vehicle’s body electronics. This VIN-programmed BCM is the definitive solution to restore order and reliability to your vehicle, serving as a direct replacement for part numbers 15064149, 15116066, and others.
The BCM is the command center for features you use every day, including interior and exterior lighting, power windows and locks, the security system, windshield wipers, and climate controls. When it fails, it can cause a cascade of confusing and frustrating problems across your Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, or Cadillac Escalade.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving its owner crazy. The radio would cut out, the dome light wouldn’t turn off, and the driver’s side window was stuck down. He had already replaced the window switch and checked fuses with no luck. A quick scan showed multiple communication codes pointing to the BCM. We installed one of our pre-programmed modules, and in less than 10 minutes, every single issue was resolved. It’s a perfect example of how one failing module can create a host of seemingly unrelated problems.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways. Look out for these common symptoms to confirm you’re targeting the right part for your repair:
- ✔ Intermittent or non-functional HVAC controls and blower motor.
- ✔ Power windows, door locks, or mirrors that work sporadically or not at all.
- ✔ An active airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Security system malfunctions, leading to a no-start condition or alarm issues.
- ✔ Inconsistent operation of interior or exterior lights.
- ✔ Communication errors with other vehicle modules.

Simple Installation and Post-Install Notes
Installation is straightforward for the average DIYer. The BCM is typically 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 programming handles the heavy lifting, 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. In some cases, a brake pedal position relearn may also be needed. Best of all, there is no core charge, so you don’t have to worry about sending the old part back.
