Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical issues in your Cadillac Escalade, Chevrolet Silverado, or GMC Sierra? Flickering lights, unresponsive power windows, a malfunctioning security system, or erratic HVAC controls are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing problems. This genuine GM Body Control Module, interchangeable with part number 25971916, arrives pre-programmed to your vehicle’s specific VIN, offering a direct, plug-and-play solution to get you back on the road without a costly trip to the dealership.
From the Diagnostic Bay
We had a 2010 Silverado 1500 in the shop that was driving the owner crazy. The radio would turn on and off, the dome light wouldn’t work, and the power locks were intermittent. He had already replaced the battery and checked all the fuses. After connecting our scanner, we saw multiple communication loss codes with various modules. Instead of chasing electrical gremlins for hours, we went straight to the BCM. A quick swap with a VIN-programmed unit like this one solved every single issue in under 10 minutes. It’s often the central cause for multiple, seemingly unrelated electrical faults.
Is Your Vehicle Showing These BCM Failure Symptoms?
- ✔ Power windows, door locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights staying on, not turning on, or flickering.
- ✔ HVAC and climate control functions are inoperative or blower motor issues.
- ✔ Vehicle security system malfunctioning, causing no-start conditions or false alarms.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Wipers not working correctly or activating randomly.
- ✔ Multiple diagnostic trouble codes (DTCs) related to body systems.

Installation and Post-Install Procedures
Physically installing the BCM is straightforward. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. While our VIN programming handles the majority of the setup, some vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
Best of all, there is no core charge for this part. You can keep your old module without the hassle of returning it.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and HVAC controls.
Is this BCM difficult to install?
The physical installation is very simple, usually taking less than 10 minutes. It’s located under the steering column and just requires unplugging the old one and plugging in the new one.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and security information onto the BCM. This ensures it communicates correctly with other modules and that all your vehicle’s features work as intended without needing a trip to the dealer.
What if my airbag light is on after I install this new BCM?
This is a common security measure. A repair shop with a high-level scan tool will need to perform an ‘SDM key relearn’ or ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag module.
Does this part fit vehicles other than the Escalade ESV?
Yes, this BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Chevrolet Silverado, Suburban, Tahoe, Avalanche, and the GMC Sierra and Yukon. Please check the fitment list for your specific model.
