Restore Full Electrical Function to Your GM Truck or SUV
Is your Cadillac Escalade, Chevy Silverado, or GMC Sierra plagued by baffling electrical problems? Intermittent wipers, flickering lights, non-responsive power windows, or a malfunctioning HVAC system 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 cascade of frustrating and seemingly unrelated issues. This genuine GM Body Control Module, part number 25971917, is the definitive solution to restore your vehicle’s functionality and reliability.
To eliminate the hassle and expense of a dealership visit, we pre-program this module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures it arrives ready for a true plug-and-play installation, loaded with the latest GM software updates. By matching the BCM to your VIN, we ensure seamless communication with your vehicle’s other electronic systems, resolving common Diagnostic Trouble Codes (DTCs) right out of the box.
From the Diagnostic Bay
We had a 2010 Silverado 2500 in the shop with a classic case of “gremlins.” The owner complained of the radio turning off randomly, the dome light staying on, and the driver’s side power window only working when it wanted to. He had already replaced the window switch and checked fuses. After hooking up the scanner, we saw multiple communication loss codes with various modules. Before condemning the BCM, we checked the main ground points under the dash and on the A-pillar. A loose ground bolt was the culprit. Always check your grounds! A 10-minute fix can save you from replacing a perfectly good module. If your grounds are solid and the problems persist, a faulty BCM is the next logical step.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or failing to turn on.
- ✔ HVAC and climate control systems blowing air at the wrong temperature or the blower motor not working.
- ✔ The vehicle’s security system malfunctioning, causing false alarms or preventing the engine from starting.
- ✔ An active airbag warning light on the dash, often accompanied by DTC B1001.
- ✔ Unexplained battery drain while the vehicle is parked.
- ✔ Wipers activating on their own or not responding to the switch.
Your Solution: The 2007-2011 Escalade EXT Body Control Module
This module is engineered to meet or exceed original equipment specifications, providing a dependable and long-lasting repair. By replacing your old, malfunctioning unit, you restore the precise control over all body functions that your vehicle was designed to have. Our VIN programming service makes the process as simple as possible, saving you time and money on diagnostic fees and dealership programming charges.
Installation and Post-Install Procedures
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the driver’s side dashboard, near the steering column. It can be swapped out in minutes. However, please be aware of potential post-installation steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This must be done with a professional-grade scan tool to synchronize the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and stability control function.
This is a no-hassle purchase with no core charge required. You can keep your old part without needing to send it back.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, wipers, security system, and climate controls.
Is this BCM ready to install right out of the box?
Yes. We pre-program the module to your vehicle’s VIN before shipping, so it’s ready for a plug-and-play installation without requiring a trip to the dealership for additional programming.
Why is my airbag light still on after installing the new BCM?
This is a normal security feature. The new BCM needs to be electronically ‘introduced’ to the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a compatible professional scan tool.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep or dispose of your old module at your convenience.
How do I confirm this part will fit my truck?
The best way is to match the part number from your original BCM to the numbers listed in this description. You can also use the vehicle fitment guide on this page or contact us with your VIN, and we will verify compatibility for you.
