Restore Full Electrical Function to Your Chevrolet Monte Carlo
Are you battling bizarre electrical gremlins in your 2006 or 2007 Chevy Monte Carlo? Issues like flickering interior lights, malfunctioning power windows and locks, a security light that won’t turn off, or even a no-start condition can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module, part number 15880684, is the definitive solution to get your Monte Carlo back in perfect working order.
From the Diagnostic Bay
We had a 2007 Monte Carlo SS come into the shop with a classic BCM failure story. The owner complained that his battery would be dead every other morning. He’d already replaced the battery and alternator. We performed a parasitic draw test and found a significant draw coming from the interior lighting circuit. Even with all the doors closed and the car off, the BCM was keeping the retained accessory power (RAP) relay energized, slowly draining the battery overnight. Swapping in a correctly programmed BCM fixed the draw instantly and saved the customer from the headache of constantly jump-starting his car.
Diagnosing Your 2006-2007 Monte Carlo BCM
A faulty BCM can manifest in many ways, making diagnosis tricky. If your vehicle is experiencing several of the issues below, a failing BCM is the most likely culprit. This module is the key to resolving those persistent electrical faults.
Common Failure Symptoms
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the dashboard gauges or instrument cluster lights.
- ✔ The security or anti-theft system light stays on, preventing the car from starting.
- ✔ Interior or exterior lights staying on when they shouldn’t, or not turning on at all.
- ✔ Problems with the keyless entry remote or tire pressure monitoring system (TPMS).
- ✔ Unexplained parasitic battery drain leading to a dead battery.
A True Plug-and-Play Solution
Don’t waste time and money at the dealership. We make this repair simple. When you purchase this 2006-2007 Monte Carlo BCM, we program it specifically for your vehicle using the VIN you provide. This means it arrives at your door with the latest GM software updates already installed, ready for installation. There is no need for an expensive trip to the dealer for programming. Plus, there’s no core charge, so you can keep your old part.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicle systems may require a simple relearn procedure after the new BCM is installed. This is standard for many electronic repairs.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- 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 function.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your Monte Carlo’s specific options, ensuring it works correctly right out of the box.
Is this BCM difficult to install?
The BCM in a 2006-2007 Monte Carlo is located under the driver’s side of the dashboard, near the steering column. Installation is straightforward for a DIYer with basic tools, typically involving removing a few trim panels and disconnecting electrical connectors.
Will this fix my car’s no-start problem?
If your no-start issue is caused by the factory anti-theft system (Passlock) being triggered by a faulty BCM, then yes, this part will resolve the problem. Our programming ensures it communicates correctly with your key and ignition system.
What if my airbag light comes on after I install it?
This is a normal possibility. The new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to turn the light off.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM part that has been programmed with the latest vehicle-specific software from GM. It provides OEM performance and reliability without the new-part price tag.
