Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM

Are you battling strange and frustrating electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a key fob that works intermittently, or random warning lights on the dash are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s electronics, a faulty BCM can cause widespread, unpredictable problems. This isn’t just an annoyance—it can affect vehicle security and safety systems. Stop chasing electrical gremlins and get the definitive fix with our professionally programmed GM Body Control Module.

We take the guesswork and dealer-dependency out of the repair. Simply provide your vehicle’s VIN during checkout, and our expert technicians will flash this module with the latest GM-certified software specific to your car, truck, or SUV. This means it arrives at your door ready for installation, saving you hundreds of dollars in dealership programming fees and diagnostic time. It’s the most efficient way to get your vehicle back to 100% functionality.

Is Your GM Vehicle Showing These BCM Failure Signs?

A failing GM Body Control Module can manifest in numerous ways. If you’re experiencing any of the following, a faulty BCM is the likely culprit:

• ✔ Power windows, door locks, or mirrors not working or operating erratically.
• ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
• ✔ The security system acting up, causing no-start conditions or a constantly flashing security light.
• ✔ Keyless entry remote failing to lock or unlock the doors.
• ✔ Instrument cluster gauges behaving erratically or warning lights (like ABS or Airbag) appearing for no reason.
• ✔ Communication error codes stored, such as U0140, U0155, or other U-codes indicating a loss of communication.

Your Straightforward BCM Installation Guide

Installing your new BCM is a manageable job for a DIYer with basic tools. While the exact location varies by model (see fitment list), the general process is similar.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down completely.
2. Locate the BCM: The BCM is typically found under the driver’s side or passenger’s side of the dashboard, or behind the center console. Refer to your vehicle’s service manual for the precise location.
3. Remove Trim Panels: You may need to remove plastic trim panels or the glove box to gain access to the module. Be gentle to avoid breaking any clips.
4. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
5. Install the New BCM: Mount your new, pre-programmed BCM in the same location and reconnect all electrical connectors. Ensure they click securely into place.
6. Reconnect and Test: Reinstall any trim panels you removed, then reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair.

Important Post-Installation Note: In some vehicles, additional steps may be required. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key’ procedure. A ‘Brake Pedal Position Relearn’ may also be necessary. These are standard procedures for this type of repair.
