Restore Your Vehicle’s Electronics with a Reliable, Programmed BCM
Are you chasing down bizarre electrical problems in your GM car, truck, or van? Flickering dash lights, power windows with a mind of their own, or a security system that randomly prevents your car from starting are all classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and hard-to-diagnose issues. Stop the guesswork and the expensive diagnostic fees. This is your direct-fit, reliable solution.

We provide a fully Programmed GM Body Control Module, flashed with the latest GM software and calibrated specifically to your vehicle’s VIN. This means no extra trips to the dealership for expensive programming. It arrives at your door ready for installation, saving you significant time and money. Simply provide your VIN at checkout, and our technicians will handle the rest, ensuring a seamless integration with your vehicle’s existing systems.
From the Diagnostic Bay: The Case of the Haunted Impala
I’ll never forget a 2008 Chevy Impala that came into the shop. The owner was at his wit’s end. The radio would turn on and off, the security light would flash intermittently, and sometimes the car just wouldn’t start. He’d already replaced the battery and alternator. After hooking up the scan tool, I saw a slew of U-codes (communication errors) pointing to a network issue. In my 20+ years, I’ve seen this pattern hundreds of time—it’s almost always the BCM failing internally and disrupting the entire vehicle communication network. We installed a VIN-programmed BCM, and it was like an exorcism. Every single electrical gremlin vanished. This is why a reliable, correctly Programmed GM Body Control Module is so critical.
Is Your Vehicle Showing These Classic BCM Failure Signs?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft light is illuminated, often causing a no-start condition.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Warning lights for ABS, Traction Control, or Airbags appearing without a clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0100, U0140, or other U-series codes.
- ✔ Problems with the keyless entry or remote start systems.
Your Straightforward BCM Installation Guide
While the BCM’s location varies by model, the replacement process is generally straightforward for a confident DIYer or any professional mechanic. Always consult a service manual for your specific vehicle’s details.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Locate the BCM: Depending on your model, the BCM is typically found under the driver’s or passenger’s side of the dashboard, behind a kick panel, or in the center console area. The fitment list below provides common locations.
- Disconnect and Remove: Carefully unplug the 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 New Module: Mount your new, pre-programmed BCM in place of the old one. Reconnect all electrical connectors, ensuring they click securely into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, wipers, and radio.
- Perform Final Checks: Start the vehicle. Observe the instrument cluster for any warning lights. As noted below, some vehicles may require a simple relearn procedure if a light (like the airbag light) appears.
Important Post-Installation Information
Your new BCM arrives ready to go, but in some cases, your vehicle’s other systems may need to be re-synced. These are not signs of a faulty part but a standard part of the vehicle’s security and safety protocols.
- Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be done with a compatible 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 perfect operation of the brake lights and traction control system.
- No Core Charge: We make it simple. There is no core charge on this module. You can keep your old part.
Disclaimer: Vehicle systems and procedures can vary. We always recommend consulting a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
Why do you need my VIN to program the module?
Your Vehicle Identification Number (VIN) allows us to flash the BCM with the exact software and configuration your vehicle had when it left the factory. This ensures all your specific options (like keyless entry, power seats, etc.) work correctly and makes installation a true plug-and-play process.
What exactly does a Body Control Module do?
The BCM is like the central nervous system for your vehicle’s non-engine related functions. It controls the power windows, locks, lights, wipers, security system, instrument cluster, and much more. When it fails, these systems can behave erratically.
Can I install this myself?
For many DIY enthusiasts with basic tools and experience, this is a manageable job. The key is correctly identifying the BCM’s location and carefully swapping the connectors. Our pre-programming service eliminates the most difficult step, which is software flashing.
Is there a core charge for my old part?
No, there is absolutely no core charge. You are not required to send your old BCM back to us, which saves you time and return shipping costs.
How do I know for sure that my BCM is the problem?
While the symptoms listed above are strong indicators, the best way to be certain is with a professional diagnosis. A scan tool that can communicate with the BCM and check for specific trouble codes (especially U-codes for communication loss) is the most effective diagnostic method.
What if my airbag light comes on after I install it?
This is a normal security feature on some GM vehicles. The new BCM needs to be electronically ‘introduced’ to the airbag module (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.
