Restore Full Control and End Electrical Frustration in Your GM Truck or SUV
Are you chasing down bizarre electrical issues in your Silverado, Sierra, or Tahoe? Flickering lights, unresponsive power windows, a dead HVAC blower, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). Stop wasting time and money on guesswork. This OEM-quality, VIN-programmed BCM, interchangeable with part number 15136225, is the definitive, plug-and-play solution to restore your vehicle’s electronic systems to perfect working order.
Common Symptoms & Your Solution
A faulty BCM can turn your reliable workhorse into a source of constant annoyance. If you’re experiencing any of the following, this module is the fix you need:
- Erratic or Non-Functioning Electronics: Power windows that won’t go up or down, door locks that don’t respond, and interior or exterior lights that work intermittently.
- HVAC Control Problems: Inability to control the fan speed, temperature, or vents, often leading to a blower motor that’s stuck on or won’t turn on at all.
- Warning Lights & No-Start Conditions: An illuminated airbag light (often with DTC B1001), a security light that prevents the engine from starting, or other confusing dash warnings.
- Diagnostic Trouble Codes (DTCs): A host of codes related to body systems, communication errors, and sensor inputs that all point back to a failing central module.
This Programmed 15136225 Body Control Module is engineered to resolve these issues directly, arriving at your door ready for a simple installation without requiring a trip to the dealership for expensive programming.

Expert Insight: The Hidden Cost of a Junkyard Module
You might be tempted to grab a used BCM from a salvage yard to save a few dollars. Here’s why that’s often a mistake: A used BCM is programmed to the VIN of the vehicle it came from. When you install it in your truck, it will cause communication conflicts, likely triggering the anti-theft system and preventing your engine from starting. You’ll then have to pay for a tow to a dealership or specialized shop with the expensive tools needed to reprogram it—erasing any initial savings. Our Programmed 15136225 Body Control Module completely avoids this scenario, giving you a guaranteed, straightforward repair from the start.
Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM acts as the central computer for your vehicle’s body electronics. It reads inputs from switches (like your window or headlight switch) and sensors, and then sends commands to operate things like your interior lights, power locks, wipers, HVAC blower, and more. When it fails, these systems become unreliable.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and security information onto the module. This allows it to communicate correctly with the Engine Control Module (ECM), instrument cluster, and other computers. Without the correct VIN programming, the vehicle’s anti-theft system will likely activate, and many features will not work.
Is this part difficult to install?
No, for most DIYers with basic tools, this is a very straightforward job. The BCM is typically located under the steering column or driver’s side dash. It involves disconnecting the battery, unplugging a few color-coded electrical connectors, swapping the module, and reconnecting everything. The entire process usually takes less than 15 minutes.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system (SDM). If the airbag light stays on, a mechanic with a professional-grade scan tool will need to perform a quick procedure called “Setup SDM Primary Key in BCM.” This is a simple sync procedure, not a full reprogramming.
Will this fix my specific electrical problem?
This Programmed 15136225 Body Control Module is the solution for the vast majority of issues listed, such as faulty lights, locks, windows, and HVAC controls. If you have confirmed through diagnostics that the BCM is the source of the failure, this part is the correct fix.
