Restore Full Functionality to Your GM Vehicle’s Electronics
Are you battling frustrating electrical problems in your Chevrolet, GMC, Cadillac, or other GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a persistent security light, or a dead battery are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your car’s comfort and convenience features. When it fails, it can cause a wide array of confusing and unpredictable symptoms. This replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a simple and effective repair.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security or anti-theft system light is illuminated, or the vehicle won’t start.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ HVAC (A/C and heater) controls not responding correctly.
- ✔ Keyless entry remote not working reliably.
- ✔ Communication error codes (U-codes) stored in the system.

Installation and Post-Install Notes
Installation is typically plug-and-play. Locate your old BCM (often found under the dash on the driver’s side or in the center console area), disconnect the battery, swap the modules, and reconnect the battery. While the core functions will work immediately, some vehicles may require a simple relearn procedure for specific systems:
- Airbag System Sync: If the airbag light is on 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and stability control function.

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 electronic body functions not related to the engine. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your specific make, model, year, and factory options. This ensures the module works correctly right out of the box without needing a trip to the dealer.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. It involves disconnecting the battery, locating and unplugging the old BCM, and plugging in the new one. The location varies by model but is typically under the dashboard.
Will I need to do any additional programming?
No, the main programming is done by us before shipping. However, as noted, some vehicles may require a simple ‘relearn’ or ‘sync’ procedure for the airbag or brake systems, which requires a professional-grade scan tool.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, failed BCM back to us. The price you pay is the final price, with no additional deposit or return shipping required.
