Is Your Monte Carlo Acting Possessed? The BCM is Likely the Culprit.
If you’re dealing with a frustrating mix of electrical gremlins in your 2006-2007 Chevrolet Monte Carlo—like power windows that won’t budge, door locks with a mind of their own, intermittent security lights, or dashboard warnings that make no sense—you’re not alone. As a technician with over two decades of experience, I’ve seen these exact symptoms hundreds of times. The root cause is almost always a failing Body Control Module (BCM). This module is the central command center for your car’s body electronics, and when it starts to fail, it can make driving a nightmare.
Don’t let a faulty module sideline your car or force you into an expensive dealership visit. We offer a reliable, cost-effective solution: a replacement Body Control Module, part number 15828601, that arrives at your door pre-programmed for your specific vehicle. Simply provide us with your VIN during checkout, and our experts will flash the module with the latest GM software. This ensures it communicates perfectly with your Monte Carlo’s existing systems, saving you the time, cost, and hassle of dealer-only programming.
Common Signs of a Failing BCM
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ The security or anti-theft system light stays on, preventing the car from starting.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The instrument cluster displays incorrect information or warning lights are falsely triggered.
- ✔ Communication error codes, such as U0140, are stored in the system.
- ✔ The radio or climate controls stop working intermittently.
A Technician’s Notebook: The Monte Carlo That Wouldn’t Cooperate
I remember a 2006 Monte Carlo SS that came into the shop with a truly bizarre set of issues. The horn would honk when the driver used the right turn signal, and the power locks would cycle every time the brake was pressed. The owner had already replaced the battery and checked all the fuses. A quick scan showed a flurry of communication codes. This pointed directly to a corrupted BCM. Instead of a complex wiring repair, the fix was a new, properly programmed BCM. Once installed, all the strange electrical behavior vanished. This case highlights how a single failing module can create widespread, confusing symptoms, and why a correctly programmed replacement is the definitive solution.
A Straightforward Guide to Installation
For the 2006-2007 Monte Carlo, the BCM is located on the left-hand side of the steering column, making it accessible for a confident DIYer. Follow these steps for a smooth installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes before starting work.
- Access the Module: Remove the lower dash panel beneath the steering wheel to gain clear access to the BCM. It’s typically held in place by a few screws or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Pay attention to the locking tabs to avoid damaging them. Once disconnected, remove any mounting hardware and take out the old module.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely fasten it. Reconnect all the electrical connectors, making sure they click firmly into place.
- Final Steps: Reinstall the lower dash panel and reconnect the negative battery terminal. Start the vehicle to confirm that the primary functions are restored.
Important Post-Installation Information
While our VIN programming handles the critical setup, some GM vehicles may require additional syncing procedures after a new BCM is installed. These are typically performed with a bi-directional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a procedure called “Setup SDM Primary Key in BCM” is needed to sync the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: We are not responsible for any labor costs. While this is often a DIY-friendly job, we always recommend consulting a factory service manual or a qualified technician if you are unsure about any step. Best of all, there is no core charge for this part. You can keep your old module.

Frequently Asked Questions
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. Just provide your vehicle’s VIN at checkout, and the BCM will arrive ready for installation with the latest GM software.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your car that manages and controls various electronic accessories, such as power windows, locks, lights, the security system, and interior chimes.
Is this part difficult to install?
For someone with basic mechanical skills, this is a manageable job. The BCM on a 2006-2007 Monte Carlo is located under the dash by the steering column. No special tools are required for the physical replacement.
Will this fix my car’s security light issue?
Yes, a faulty BCM is one of the most common causes of a persistent security light and no-start conditions on these GM vehicles. Replacing it with our programmed module is a very effective solution for this problem.
What if my original part number is different?
This BCM replaces a long list of interchangeable GM part numbers. As long as your original part number is on our cross-reference list, this module will work perfectly for your vehicle after programming.
Is there a core charge?
No, we do not require you to send your old BCM back. There is no core charge associated with this purchase.
