Restore Full Electronic Functionality to Your Vehicle
Is your 2007-2009 Chevrolet Equinox or other compatible GM vehicle plagued by strange electrical problems? Flickering lights, malfunctioning power windows, a temperamental security system, or warning lights that won’t turn off are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and unpredictable issues. This direct-replacement Body Control Module, part number 20921435, is the definitive solution to get your vehicle’s accessories and systems operating like new again.
Unlike a standard part from a dealership or local store, this module arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We handle the complex part of flashing the unit with the latest GM software updates, ensuring seamless integration and optimal performance. This means you can bypass the expensive and time-consuming trip to the dealer for programming, saving you both time and money. Simply provide your VIN after purchase, and we’ll take care of the rest.
Expert Pro Tip: Before condemning your BCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (battery to chassis, chassis to engine). A weak battery or a corroded ground wire can cause low voltage conditions that mimic the symptoms of a faulty BCM. A simple check can sometimes save you the cost of a replacement part.
Common Symptoms of a Failing BCM
If you’re unsure whether your BCM is the culprit, review this list of common failure indicators. A faulty module is often the source of these problems:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or exterior lights staying on or not working at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Intermittent or complete failure of the radio and instrument cluster gauges.
- ✔ Unexplained battery drain that occurs when the vehicle is off.
- ✔ False warning lights appearing on the dashboard (e.g., airbag, brake).
- ✔ Horn honking unexpectedly or not working when pressed.
Why Choose Our 2007-2009 Equinox Body Control Module?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine OEM module and professionally program it using your vehicle’s VIN. This critical step ensures that all the specific options and features your vehicle was built with are recognized by the new BCM. From power seat settings to specific lighting packages, our programming process guarantees that the module communicates perfectly with all other computers in your vehicle, restoring factory functionality without any compromises.
Installation and Post-Install Procedures
Physically installing the BCM is typically a straightforward process, often located under the dash on the driver’s or passenger’s side. However, after the new module is connected, a couple of additional steps, known as relearn procedures, may be required to fully sync the vehicle’s systems.
- 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’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary. This ensures the brake lights and traction control system function as intended.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do in my vehicle?
The BCM acts as a central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and the instrument panel. It receives inputs from switches and sensors and sends commands to the corresponding components.
Is this BCM truly plug-and-play?
Yes, for most functions. Because we pre-program the module to your vehicle’s VIN, it will be ready for installation right out of the box, eliminating the need for dealer programming. However, as noted, certain systems like the airbag or brake pedal sensor may require a simple relearn procedure with a diagnostic tool after installation.
What information do you need from me to program it?
We need your vehicle’s 17-digit Vehicle Identification Number (VIN). You can typically find this on your driver’s side door jamb sticker, your insurance card, or visible through the windshield on the driver’s side dashboard. Please provide this to us after you complete your purchase.
What happens if I don’t perform the post-install procedures?
If a post-install procedure is required and not performed, you may have a persistent warning light (like the airbag light) or a system that doesn’t function correctly (like the traction control). The vehicle will likely still run and drive, but it will not be fully operational until these final sync procedures are completed.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
