Restore Full Electrical Function to Your Vehicle
Is your Chevrolet Equinox or other GM vehicle suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows, or random warning indicators on your dash are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. This replacement Body Control Module, part number 20815898, is the definitive solution to restore your vehicle’s electronic stability and functionality.
We take the guesswork and high cost out of the equation. Unlike a trip to the dealership, which involves towing fees, diagnostic charges, and expensive programming, our service provides a direct, ready-to-install solution. Simply provide your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM factory software specific to your car. This ensures that when the part arrives, it’s a true plug-and-play component, ready to resolve your issues and get you back on the road with confidence.
From the Diagnostic Bay
We had a 2008 GMC Acadia come into the shop with a complaint that would drive any owner crazy. The interior lights would randomly turn on while driving, the radio would shut off, and the liftgate would refuse to open. The customer had already replaced the battery, thinking it was a simple power issue. After connecting our scan tool, we saw multiple communication loss codes (U-codes) pointing to the BCM. Instead of a complex and costly diagnostic chase, we sourced a VIN-programmed BCM. The installation took less than an hour, and instantly, all the ghost-like electrical problems vanished. It’s a perfect example of how a failing BCM can mimic a dozen other issues, and how the right, pre-programmed part is the fastest path to a reliable fix.
Common Symptoms of a Failing BCM
- ✔️ Erratic or non-functional power windows, door locks, and mirrors.
- ✔️ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔️ The security system engaging randomly, preventing the vehicle from starting.
- ✔️ Unresponsive remote keyless entry (fob not working).
- ✔️ Dashboard warning lights (like ABS, Airbag, or Check Engine) illuminating without a clear cause.
- ✔️ Intermittent operation of the radio, climate control, or windshield wipers.
- ✔️ Rapid battery drain when the vehicle is turned off.
Why Choose Our Programmed 2007-2009 Equinox Body Control Module?
This isn’t just a replacement part; it’s a complete service designed for you. By handling the programming before shipment, we eliminate the most difficult step of the repair process. The module arrives ready for installation, saving you hundreds of dollars in dealership labor and programming fees.

Installation and Post-Install Considerations
Physical installation is straightforward for those with basic mechanical skills. The BCM is typically located in the center dash or under the steering column. After disconnecting the battery, you can unbolt the original module, disconnect its wiring harnesses, and install the new one in its place. Once reconnected, your vehicle’s core functions should be restored. However, depending on your specific model, a couple of additional steps may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper operation of brake lights and stability control systems.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

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 a wide range of non-engine-related functions. This includes power windows, door locks, interior and exterior lighting, security systems, climate controls, and more. It acts as a central hub for these electronic features.
Do I need to program this module after I receive it?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process as simple as possible, saving you a trip to the dealership for expensive programming.
Where is the BCM located on my 2007-2009 Equinox?
On the 2007-2009 Chevrolet Equinox and Pontiac Torrent, the Body Control Module is typically located in the center dash console area, often accessible by removing panels around the radio or glove box.
What happens if I forget to provide my VIN?
Providing your VIN is a critical step. We cannot program and ship your BCM without it. If you forget to add it during checkout, our customer service team will contact you to retrieve the information, which may delay your order.
Will this BCM fix my specific electrical problem?
This module will correct issues that are directly caused by a faulty BCM. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional scan tool. Most basic OBD-II code readers cannot perform these functions. If these procedures are necessary, you may need to visit a local repair shop.
