Tired of Unpredictable Electrical Gremlins in Your Chevy?
Are you dealing with flickering lights, power windows that won’t cooperate, a security light that stays on, or a car that intermittently refuses to start? These frustrating and unpredictable issues often point to a single culprit: a failing Body Control Module (BCM). In your 2000-2004 Monte Carlo or Impala, the BCM is the central command for most of the vehicle’s body electronics. When it fails, it can make your reliable daily driver feel like a source of constant annoyance. This isn’t just an inconvenience; it can affect your car’s security and your peace of mind. Stop guessing and replace the root of the problem with a solution designed to work right out of the box.

If you’re experiencing any of the following, a failing BCM is the likely cause. This pre-programmed module is the definitive, dealership-alternative solution to restore your vehicle’s proper function. It’s time to fix it right and get your car back to being the dependable vehicle you count on.
- Erratic power window and door lock operation

An Expert’s Note on VIN Programming
“Back in the day, you could often swap modules between similar cars. With vehicles from the 2000s onward, that’s a recipe for disaster. The BCM is tied directly to your car’s specific options and, most importantly, its security system via the Vehicle Identification Number (VIN). Installing a non-programmed module will, at best, not work correctly and, at worst, immobilize your vehicle completely. We handle this critical programming step for you *before* we ship, saving you a costly trip to the dealership and the headache of a car that won’t start after the repair. It’s the single most important step to a successful BCM replacement.”

Frequently Asked Questions
Do I absolutely have to provide my VIN?
Yes. Providing your vehicle’s 17-digit VIN is mandatory. We cannot ship the module without it. This step is crucial for programming the BCM to match your car’s specific features and security system, ensuring it works correctly upon installation.
Will I need to perform any procedures after installation?
Possibly. In some cases, you may need a professional scan tool to perform an ‘Airbag System Sync’ if the airbag light comes on, or a ‘Brake Pedal Position Relearn’. These are simple procedures for any qualified technician but are important for full system integration.
Is this a difficult part to replace myself?
For someone with moderate mechanical experience, it is a manageable job. The BCM is typically located under the driver’s side of the dashboard. The most important steps are disconnecting the battery first and carefully swapping the electrical connectors. Always consult a service manual for your specific vehicle if you are unsure.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, proper diagnosis is key. If multiple, unrelated electrical systems are failing simultaneously (e.g., windows, locks, and security), the BCM is the most likely cause. A diagnostic scan by a professional technician can often confirm a faulty BCM by identifying communication error codes.

This BCM is a direct replacement for the following GM service numbers: 10323612, 10340320, 10350647, 10432318, 10432571, 10438145, and 10445875.
