End the Electrical Headaches in Your Chevy Impala
If you’re dealing with a 2006-2013 Impala that seems to have a mind of its own—flickering lights, power windows that won’t budge, a security light that stays on, or a car that refuses to start—you’re not alone. These are classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM goes bad, it can cause a cascade of frustrating and seemingly unrelated problems. It’s a common issue, and I’ve seen it countless times on the service floor.
Instead of spending a fortune at the dealership for diagnostics and programming, we offer a straightforward, reliable solution. This is a direct-replacement 2006-2013 Impala Body Control Module that arrives at your door fully programmed to your car’s specific Vehicle Identification Number (VIN). We install the latest GM software updates, ensuring optimal performance and compatibility. This eliminates the most difficult part of the job, allowing you to get your car back to 100% with a simple installation.
Case Study: A Tricky Diagnosis
A customer brought in their ’09 Impala with a complaint that was all over the map. The radio would cut out, the driver’s side power window worked intermittently, and sometimes the car wouldn’t start, showing only a ‘Service Theft System’ message. They had already replaced the battery and checked the fuses. After connecting my scan tool, I saw multiple communication loss codes (U-codes) pointing to the BCM. These modules are notorious for internal circuit board failures causing these exact gremlin-like issues. We installed a VIN-programmed BCM, and all the problems vanished instantly. It’s a textbook example of how a single module can disrupt the entire vehicle.
Common Signs of a Failing BCM
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security or anti-theft system light is illuminated, preventing the car from starting.
- ✔ Erratic behavior from the dashboard gauges or warning lights.
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes.
- ✔ Horn honking unexpectedly or not working when pressed.
A Straightforward Guide to Your BCM Replacement
Installing your new 2006-2013 Impala Body Control Module is a manageable job for a confident DIYer. On the Impala, the BCM is typically located on the left (driver’s) side of the dashboard, often near the steering column or behind the lower dash panel.
- Safety First: Always disconnect the negative terminal from your car’s battery and wait a few minutes to ensure all systems are powered down.
- Access the Module: You will likely need to remove the lower dash panel beneath the steering wheel to gain access to the BCM. This usually involves a few screws or clips.
- Identify and Disconnect: Locate the BCM. It’s a small plastic box with several large multi-pin electrical connectors. Carefully release the locking tabs on each connector and pull them straight out.
- Remove the Old BCM: Unbolt or unclip the old module from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors firmly until they click into place.
- Final Steps: Reinstall the dash panel and reconnect the negative battery terminal. Your installation is complete.
Important Post-Installation Information
Because this 2006-2013 Impala Body Control Module is pre-programmed, it’s designed for a near plug-and-play experience. However, in some vehicles, additional steps may be required to sync all systems:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor relearn might be necessary. This can also be performed with a capable scan tool.
- No Core Charge: We do not require you to send your old part back. There is no core charge associated with this purchase.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult a certified technician if you are unsure about any procedure.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle the programming for you before we ship. Just provide your vehicle’s VIN during or after checkout, and it will arrive ready to install with the latest GM software.
What exactly does a Body Control Module do?
The BCM acts as the main computer for your vehicle’s body electronics. It controls functions not related to the engine, such as power windows, locks, lights, security system, wipers, and dashboard warnings.
Where is the BCM located on my 2008 Impala?
For the 2006-2013 Chevrolet Impala, the BCM is typically found behind the lower dash panel on the driver’s side, to the left of the steering column.
What happens after I install it?
In most cases, the vehicle will start and function normally immediately. In some instances, as noted above, a relearn procedure for the airbag system or brake pedal position sensor may be required if you have warning lights for those systems.
Is there a core charge or do I have to send my old part back?
No, there is absolutely no core charge. You can keep your old module.
