Tired of Your Vehicle’s Electrical Gremlins?
Are you dealing with frustrating and unpredictable electrical issues in your GM vehicle? Flickering dashboard lights, power windows with a mind of their own, door locks that don’t respond, or a security system that prevents your car from starting can turn any drive into a stressful ordeal. These aren’t just annoyances; they are classic signs of a failing Body Control Module (BCM), the central nervous system for your vehicle’s comfort and convenience features.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, power locks, interior and exterior lighting, the security system, wipers, and sometimes even the climate control and radio.
Why do you need my VIN?
Your vehicle’s 17-digit VIN (Vehicle Identification Number) is crucial. It allows us to load the exact software and settings your specific vehicle requires based on its factory-installed options. This ensures all features work correctly right out of the box.
Is this part difficult to install?
For someone with moderate mechanical skill, the installation is typically straightforward. The BCM is usually located under the dashboard on the driver’s or passenger’s side. The main task is disconnecting the battery and then carefully swapping the electrical connectors from the old module to the new one. No special programming tools are needed on your end.
What are the post-installation procedures mentioned?
In some GM vehicles, after installing a new BCM, a couple of simple relearn procedures may be needed. This can include syncing the airbag system (SDM) or recalibrating the brake pedal position sensor. These procedures often require a professional scan tool but are only necessary if specific warning lights appear after installation. We provide clear information on these potential steps with your purchase.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep, discard, or recycle your original module at your convenience without any penalty.

This Programmed GM Body Control Module 15921353 is the solution for a very wide range of electrical issues. If your symptoms match those listed (erratic lights, failing power accessories, security faults), it is the most common and effective repair. It resolves the root cause of these problems by replacing the faulty central computer.
