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

Are you battling frustrating electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows or door locks, a security system that acts up, or strange warning messages on your dash are all classic signs of a failing Body Control Module (BCM). As the central command center for your car’s body electronics, a faulty BCM can cause a cascade of confusing issues. This isn’t just an annoyance; it can affect your vehicle’s security and safety. We offer a reliable, straightforward solution: a professionally programmed GM Body Control Module, ready for installation right out of the box.

Is Your Vehicle Showing These Symptoms?

A failing BCM can be tricky to diagnose because the symptoms seem unrelated. If you’re experiencing any of the following, your GM Body Control Module is the likely culprit:

• ✔ Power windows, mirrors, or door locks working intermittently or not at all.
• ✔ Interior or exterior lights flickering, staying on, or not turning on.
• ✔ The security or anti-theft system light is illuminated, and the vehicle may not start.
• ✔ The horn sounds randomly or doesn’t work.
• ✔ Wipers behaving erratically.
• ✔ Communication error codes (often U-codes like U0140, U0155) stored in the system.
• ✔ False warnings on the instrument cluster (e.g., “Door Ajar”).

The Critical Advantage: VIN-Specific Programming

Don’t settle for a used BCM from a junkyard that will require an expensive trip to the dealer for programming. We take the guesswork and extra cost out of the equation. When you purchase from us, you simply provide your vehicle’s VIN. Our technicians will then program the module with the latest, most stable software directly from GM. This ensures the BCM is a perfect match for your vehicle’s specific options and configuration, restoring function and communication just as the factory intended.

Your Straightforward BCM Installation Guide

Replacing your BCM is a job most DIYers with basic tools can handle. Follow these general steps to get your vehicle back in top shape.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
2. Locate the BCM: The Body Control Module is typically found under the driver’s or passenger’s side of the dashboard, or behind a kick panel. Its exact location varies by model (see fitment list for clues).
3. Disconnect and Remove: Carefully unplug the electrical connectors. Most have a locking tab that needs to be pressed or lifted. Once disconnected, unbolt the old module and remove it from the vehicle.
4. Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all related functions: lights, locks, windows, wipers, and horn.
6. Perform Relearns (If Needed): In some cases, you may need a professional scan tool for post-installation procedures like an Airbag System Sync or a Brake Pedal Position Relearn. See our FAQ for more details.
