Is your 2000-2004 Chevrolet Impala or Monte Carlo suffering from strange and unpredictable electrical problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and locks to the interior lights and security system. When the BCM begins to fail, it can cause a wide range of frustrating issues that are often difficult to diagnose. This isn’t just an inconvenience; a faulty BCM can affect vehicle security and safety systems.
This is a direct replacement Body Control Module, part number 10350647, which is compatible with a range of original service numbers. We take the guesswork and high dealership costs out of the equation. Each module is professionally programmed with the latest GM software updates specifically to your vehicle’s VIN. This ensures a seamless installation process and restores your car’s electronic functions to factory specifications.
Common Symptoms of a Failing 2000-2004 Impala BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The anti-theft or security system malfunctioning, preventing the car from starting.
- ✔ Keyless entry remote failing to lock or unlock the doors.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with diagnostic scan tools.
- ✔ False warning messages appearing on the instrument cluster.
Plug-and-Play Installation & Post-Install Notes
Because we program the module to your VIN before shipping, the installation is straightforward for a DIY mechanic or any professional technician. It’s a true plug-and-play solution. However, on some vehicles, additional steps may be required after installation:
- Airbag System Sync: If the airbag warning light is illuminated after you install the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be needed to ensure proper function of the brake lights and traction control system.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the specific software and settings for your car’s exact options and features. This makes the unit plug-and-play and avoids a costly trip to the dealership for programming.
Is this part difficult to install?
The BCM is typically located under the driver’s side of the dashboard. Physical installation involves disconnecting the battery and swapping a few electrical connectors. Most DIYers with basic tools can perform the swap in under an hour. However, post-installation procedures may require a professional scan tool.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to your car’s airbag module. A technician with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
