Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Flickering lights, unresponsive power windows, a malfunctioning security system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). This vital component is the central hub for your vehicle’s body electronics. When it fails, it can cause a cascade of seemingly unrelated problems. This OEM-quality replacement BCM, corresponding to part numbers 15926094 and 25844480, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
Diagnosing a Faulty GM Body Control Module
The BCM manages a wide array of comfort, convenience, and security features. A failure can manifest in many ways, often making diagnosis tricky. If you’re experiencing any of the following, your BCM is the most likely culprit.
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ HVAC and climate control systems not working correctly (e.g., blower motor issues).
- ✔ Airbag warning light illuminated on the dash, often with a B1001 diagnostic trouble code.
- ✔ Vehicle security system acting up, causing no-start or stalling conditions.
- ✔ Intermittent operation of windshield wipers.
The Plug-and-Play Advantage for Your Yukon XL Body Control Module
Typically, replacing a BCM requires a trip to the dealership for expensive and time-consuming programming. Our modules eliminate this step entirely. We flash the unit with the latest GM software updates and program it specifically to your vehicle’s VIN before it ships. This ensures that it communicates perfectly with your truck’s other electronic systems right out of the box. This is not just a convenience; it’s essential for proper function of integrated systems like the airbag (SRS) and anti-theft deterrents. This module is a direct replacement for a wide range of part numbers, including: 25835966, 15263363, 15943678, 15926094, 25844480, 20939137, and 22860591.
Installation and Post-Install Notes
Installation is straightforward. The BCM is located under the driver’s side dashboard, near the steering column. Simply disconnect the negative battery terminal, unplug the electrical connectors from the old module, remove it, and install the new one. Reconnect everything and you’re done. In most cases, no further action is needed. However, if your airbag light was on due to a B1001 code, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function to sync the new BCM with the airbag system. This is a simple procedure found in the ‘Special Functions’ menu of most advanced scanners.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central command for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows, door locks, wipers, HVAC system, and security features.
Is this BCM ready to install when I receive it?
Yes! This is a key benefit. We pre-program the module to your vehicle’s specific VIN before shipping. This means no additional programming or dealer visits are required for installation. It’s a true plug-and-play solution.
What if my airbag light stays on after installing the new BCM?
If the airbag light is on, it typically means the new BCM needs to be electronically ‘introduced’ to the airbag’s Sensing and Diagnostic Module (SDM). A technician with an advanced scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I have to send my old part back?
No. There is no core charge for this part. You can keep or dispose of your old module without any hassle.
How can I be sure this fits my 2008 GMC Sierra or 2010 Chevy Tahoe?
This module fits a wide range of 2007-2013 GM trucks and SUVs. The best way to confirm fitment is to match your original part number to one of the compatible numbers listed on our product page or use our vehicle selector tool.
