Restore Full Electrical Function to Your GM Vehicle
Are you battling bizarre electrical issues in your vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or an engine that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it fails, it can create a cascade of frustrating and seemingly unrelated problems. This replacement BCM, part number 25934762, is the definitive solution to restore order and reliability to your vehicle’s essential functions.

It arrives at your door ready for installation, saving you time, money, and the hassle of a trip to the dealership.

Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Malfunctioning keyless entry and security system alerts.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Warning lights on the dashboard, such as the airbag or service vehicle light.
- ✔ Wipers or horn activating unexpectedly.
Installation and Post-Install Considerations
Physical installation is typically straightforward, as the module is designed to be a direct replacement. However, because the BCM communicates with other critical systems, some vehicles may require a ‘relearn’ or ‘sync’ procedure after the new module is installed. For example, if your airbag warning light is on after installation, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary on certain models to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the main computer for your vehicle’s body and comfort electronics. It controls functions like power windows, locks, lights, wipers, the security system, and more, ensuring they all work together as intended.
Does this module need to be programmed by a dealer?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s 17-digit VIN when you order, and it will arrive ready for installation with the latest GM software for your specific vehicle.
Is this a simple plug-and-play installation?
For many vehicles, it is. You disconnect the old module and connect the new one. However, some models may require additional relearn procedures for systems like the airbags or brake pedal position sensor, which may require a professional diagnostic tool.
How do I provide my VIN?
You can add your VIN to the notes section during checkout. If you forget, we will contact you via email after your purchase to request it. We cannot ship your module until we have the VIN to program it.
