Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical problems in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Issues like flickering lights, unresponsive power windows, erratic door locks, or a dead HVAC system often point to a single culprit: a failing Body Control Module (BCM). This vital component acts as the central computer for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and disruptive symptoms. This genuine OEM-quality BCM, part number 10367690 (interchangeable with 15116066 and others), is the definitive solution, pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving its owner crazy. The radio would turn on and off by itself, the dome light wouldn’t work, and occasionally the truck would refuse to start, showing a ‘Security’ light on the dash. The owner had already replaced the battery and checked the grounds. After a quick scan, we saw multiple communication codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. In under 10 minutes, the truck started right up, and every single electrical gremlin was gone. It’s a common story, and this part is the fast, reliable fix.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Unresponsive or malfunctioning power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ HVAC and climate control systems not functioning correctly or at all.
- ✔ An active airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Security system issues, including no-start conditions where the engine won’t crank.
- ✔ Intermittent or non-working windshield wipers.
Technical Specifications and Installation for your 2003-2006 Yukon XL BCM
This module is built to strict OEM standards for reliability and longevity. The most significant benefit is our complimentary VIN programming service. We flash the module with your vehicle’s specific information and the latest GM software updates before it ships. This means no expensive programming sessions at a dealership are required. Simply locate your old BCM (typically under the driver’s side dash near the steering column), disconnect the battery, swap the modules, and reconnect. The entire process is straightforward for any DIY mechanic.
Post-Installation Notes: While the module is plug-and-play, some vehicles may require a simple relearn procedure. If your airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with the airbag system. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. There is no core charge for this part, so you can keep your old module without hassle.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls your vehicle’s non-engine related electronic systems. This includes power windows, locks, lights, wipers, the security system, and HVAC controls.
Is this BCM difficult to install?
No, installation is typically very simple and takes less than 15 minutes. It involves disconnecting the battery, locating the old BCM under the dash, unplugging its connectors, and plugging in the new one.
Will I need to go to the dealership after installing this part?
No. This BCM comes pre-programmed to your vehicle’s VIN, eliminating the need for any additional programming at a dealership, which saves you time and money.
What if my airbag light is on after installation?
If the airbag light appears, it means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a professional-grade scan tool.
