Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you battling bizarre electrical issues in your vehicle? Flickering lights, malfunctioning power windows, a horn that won’t quit, or worse, a car that refuses to start? These are classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of daily frustration. This isn’t just an inconvenience; it’s a critical component that manages everything from your interior lights and security system to your power locks and windows.
We offer a straightforward and reliable fix. This listing is for a replacement Body Control Module, compatible with part numbers like 13583542 and 13580696. The best part? We handle all the complex programming for you. Simply purchase this service, ship your original BCM to us, and we’ll clone all the essential data—including VIN, mileage, and key information—onto this replacement unit. We then ship it back to you, ready for a simple, plug-and-play installation. This process eliminates the need for expensive dealership visits and specialized programming tools, getting you back on the road quickly and affordably.
A Technician’s Notebook: The Common Culprit
Just last week, a 2012 Chevy Equinox came into my bay with a laundry list of electrical complaints—the radio was dead, the dome light wouldn’t turn off, and the remote key fob was useless. The customer had already replaced the battery, thinking it was a simple power issue. After a quick scan, I found multiple U-codes (communication errors) pointing to the BCM. On these GM platforms, one of the most common causes of BCM failure I see is water intrusion from a clogged sunroof drain or a degraded windshield seal. The BCM is often located in the kick panel or under the dash, making it vulnerable. This is why a simple visual inspection of your old module for corrosion can often confirm the diagnosis before you even spend a dime on diagnostics.
Is Your GM Vehicle Exhibiting These BCM Failure Signs?
- ✔ Inconsistent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system acting erratically or preventing the engine from starting.
- ✔ The horn blaring unexpectedly or not working when needed.
- ✔ No communication with the BCM when using a diagnostic scan tool (often showing U-codes like U0140).
- ✔ Complete no-start condition where the dashboard lights up but the engine won’t crank.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2013 Spark, the BCM is typically found in the left lower a-pillar area. For other models, its location varies (see fitment list below). Consult a service manual if you’re unsure.
- ✔ Remove Trim Panels: Carefully remove any plastic trim or kick panels necessary to access the module. Use a trim removal tool to avoid breaking any clips.
- ✔ Disconnect and Remove: Unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the Replacement: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors firmly until they click into place.
- ✔ Final Steps: Re-install any trim panels you removed and reconnect the negative battery terminal. Start the vehicle to confirm that the primary functions are restored.
Important Post-Installation Information
Our cloning service makes this a near plug-and-play repair. However, in some vehicles, certain safety systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your 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 airbag system with the BCM.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on some models.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for your specific make and model.
