Restore Full Electrical Function to Your GM Truck or SUV
Are you battling a storm of strange electrical issues in your Chevrolet Silverado, GMC Sierra, or Tahoe? A faulty Body Control Module (BCM) is often the culprit behind problems like malfunctioning power windows, erratic door locks, dead HVAC controls, or a persistent airbag light. This OEM-quality replacement BCM, part number 15926094, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
The BCM acts as the central command center for your truck’s body electronics. When it fails, it can cause a wide range of frustrating and difficult-to-diagnose symptoms. Instead of spending a fortune on dealership diagnostics and programming fees, this module arrives at your door pre-programmed to your vehicle’s specific VIN. This ensures a seamless, plug-and-play installation that gets you back on the road quickly and confidently.
Is Your Silverado Body Control Module Failing?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Non-responsive or intermittent power windows, door locks, or mirrors.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Interior or exterior lights staying on, not turning on, or flickering.
- ✔ Vehicle security system acting up, causing no-start or stalling conditions.
- ✔ Wipers operating erratically or not at all.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs).

This isn’t just a part; it’s a complete repair solution. We program the module with the latest GM software updates using your vehicle’s VIN before it ships. This critical step eliminates the need for expensive dealer-only tools and programming procedures. The module integrates perfectly with your vehicle’s existing systems, including the anti-theft and airbag systems, for immediate functionality. It is a direct replacement for a wide range of part numbers, including 25844480, 25835966, 15943678, 20939137, and 22860591.
Installation is straightforward for any DIYer with basic tools. The BCM is located under the driver’s side dashboard, near the steering column, and can typically be swapped out in under 10 minutes. While most installations are simple, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool if the airbag light remains on. This syncs the new BCM with the airbag system. There is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
Why do I need to provide my VIN at checkout?
Providing your VIN is essential. We use it to program the Body Control Module with your vehicle’s exact software and security information. This makes the installation plug-and-play and prevents the need for a costly trip to the dealership for programming.
Is this part difficult to install myself?
The physical installation is very simple for most DIY mechanics. It’s located under the steering column and usually takes only a few minutes to swap. However, be aware that post-installation procedures, like an airbag system sync, may require a professional bidirectional scan tool.
What if my airbag light is on after installing the new BCM?
If the airbag light is on, it means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with an advanced diagnostic tool.
Do I need to return my old BCM?
No, there is absolutely no core charge for this part. You can keep your old module without any extra fees or hassle.
Will this BCM fit vehicles other than a Silverado?
Yes, this module is compatible with a wide range of 2007-2013 GM vehicles, including the GMC Sierra, Chevrolet Tahoe, Suburban, Avalanche, and Cadillac Escalade. Please verify the part number or use our fitment tool to confirm compatibility.
