Restore Full Electrical Control to Your GM Truck or SUV
Are you dealing with frustrating and unpredictable electrical issues in your Chevrolet, GMC, or Isuzu? Flickering dashboard lights, power windows that refuse to cooperate, a security system that acts up, or a battery that mysteriously drains overnight are all common indicators of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a host of problems that are difficult to diagnose. This replacement BCM is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on or not turning on).
- ✔ Malfunctioning security system or keyless entry remote.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Unexplained warning lights appearing on the instrument cluster.
- ✔ Significant parasitic battery drain, leading to a dead battery.
- ✔ Wipers or other accessories operating incorrectly.

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and hassle out of the repair process. Before we ship your module, our technicians will program it with the latest official GM software updates, specifically flashed to your vehicle’s unique 17-digit VIN. This ensures seamless communication between the BCM and all other modules in your truck, providing a true plug-and-play experience. You get a fully functional component without the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We recently worked on a 1999 GMC Jimmy where the owner was convinced he had a major wiring short. His complaint was a dead battery every single morning. He had already replaced the battery and the alternator, with no success. After a quick parasitic draw test, we isolated the issue to the BCM. It was failing to enter its ‘sleep’ mode, keeping several circuits active overnight and draining the new battery. Instead of hours spent tracing wires, the fix was this pre-programmed BCM. It solved a months-long headache in under an hour.
Simple & Straightforward Installation
Replacing the BCM is a manageable job for a confident DIYer. Located under the dash, it’s typically accessible after removing a few trim panels. Once installed, your vehicle’s core functions will be immediately restored. However, on some models, additional synchronization procedures may be necessary.
- Airbag System Sync: If the airbag warning light illuminates after installation, it means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be needed. This is also performed with a compatible diagnostic tool.
We handle the critical programming; you handle the straightforward installation. Plus, there is no core charge on this part, so you can keep your original module without the hassle of shipping it back.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and communicates with many of your vehicle’s non-engine related electronic systems. This includes lighting, power windows, security, door locks, wipers, and other comfort and convenience features.
Is this BCM ready to install when I receive it?
Yes. We program it to your vehicle’s VIN before shipping, so it’s ready for installation. In most cases, it is plug-and-play. Some vehicles may require a simple relearn procedure for systems like the airbag or brake sensor, which can be done with a compatible scan tool.
How do I provide my VIN?
After placing your order, simply reply to your order confirmation email with your vehicle’s 17-digit Vehicle Identification Number (VIN). We must have your VIN to program and ship your part.
My original part number isn’t listed, but my vehicle is. Will this work?
This module replaces a range of original part numbers. As long as your make, model, and year are listed in our fitment guide, we will program the BCM to function correctly for your specific vehicle configuration using your VIN.
What tools are needed for installation?
Basic hand tools like a socket set and screwdrivers are usually all that’s needed to access and replace the BCM under the dashboard. A professional-grade scan tool may be required for post-installation procedures if warning lights appear.
