Restore Your Equinox’s Electrical System and Drive with Confidence
Are you chasing electrical gremlins in your 2007-2009 Chevrolet Equinox? Flickering lights, malfunctioning power windows, a dead key fob, or strange warning messages on the dash are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can make your daily drive frustrating and unpredictable. This isn’t just an inconvenience; it can affect critical systems like your vehicle’s lighting and security. This replacement Body Control Module, part number 20935349, is the reliable solution to restore full functionality and peace of mind.
We take the guesswork and dealer expense out of the equation. Unlike a generic part off the shelf, this module comes with our expert Cloning Service. Simply provide your vehicle’s VIN at checkout, and our technicians will program the module with the latest GM software specific to your Equinox. This ensures a seamless installation, eliminating the need for expensive dealership programming tools. It’s a direct-fit, ready-to-install solution designed to get your vehicle back to factory-spec performance.
Case Study: A Tricky Diagnosis
I remember a 2008 Equinox that came into my shop with a truly baffling set of symptoms. The owner reported that the radio would turn on by itself, the dome lights wouldn’t turn off, and the remote start worked only intermittently. A basic scan showed a dozen communication error codes (U-codes), pointing fingers at multiple systems. A less experienced tech might have started replacing random parts. However, after 20 years of seeing this, I recognized the pattern. All these unrelated components were controlled by one central unit: the BCM. We confirmed the BCM was failing to properly network with other modules. Installing a correctly programmed 2007-2009 Equinox Body Control Module resolved all issues in one go, saving the customer hundreds in unnecessary diagnostic time and parts.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to illuminate.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ Key fob or remote entry system stops working reliably.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
- ✔ Multiple, seemingly unrelated warning lights on the instrument cluster.
- ✔ Communication DTCs like U0140 (Lost Communication With Body Control Module).
A Straightforward Guide to Installation
Replacing the BCM in your Equinox is a manageable task for the confident DIYer. Your new module is located behind the center dash console. Always prioritize safety and have a factory service manual for reference.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes for the system capacitors to discharge.
- Access the Module: Carefully remove the trim panels around the center dash and radio to gain access to the BCM. Its exact position is typically on the lower part of the center stack.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Once disconnected, unbolt the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely fasten it. Reconnect all electrical connectors, ensuring they click firmly into place.
- Post-Installation Checks: Reconnect the battery terminal. Start the vehicle and test all body functions: lights, locks, windows, radio, etc.
- Perform Relearns (If Needed): As noted below, some vehicles may require an Airbag System Sync or Brake Pedal Position Relearn if specific warning lights appear. This typically requires a professional scan tool.
Important Notes on Post-Installation Procedures
Our cloning service handles the main programming, but due to the complexity of modern vehicle networks, some security handshakes must happen inside the vehicle. After installing your 2007-2009 Equinox Body Control Module, be aware of the following potential requirements:
- Airbag System Sync: If the airbag light is on, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag module and requires a compatible professional scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary for proper brake light and traction control operation.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and vehicle-specific options from GM. This ensures the module works correctly with your Equinox’s existing systems right out of the box.
Is this a plug-and-play part?
Yes, for the most part. Our Cloning Service handles the difficult programming. You simply install it. However, as with any module replacement on a modern vehicle, some simple relearn procedures (like for the airbag or brake pedal sensor) may be required after installation if certain warning lights appear.
Do I need to return my old BCM?
No. Our service is a cloning service, not an exchange. We use your VIN to program a replacement unit. Your original module is always returned to you along with the programmed replacement unit, so there is no core charge or return required.
Can I install this myself?
Yes, if you have moderate mechanical skill and basic tools, this is a very manageable installation. The most important part is carefully removing trim panels to access the module’s location in the center dash.
What happens if my airbag light comes on after installation?
This is a known possibility and is not a sign of a defective part. It means the new BCM needs to be electronically ‘introduced’ to the airbag’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 resolve this.
Will this fix my specific problem?
This BCM will fix issues directly caused by a faulty Body Control Module. The symptoms listed above are the most common indicators. If you’re unsure, a professional diagnosis is the best way to confirm the BCM is the root cause of your vehicle’s issues.
