Programmed 2003-2007 GM BCM | Fits Silverado, Sierra | Replaces 15116065

Restore Your GM Truck or Van’s Electrical System

Are you dealing with frustrating electrical problems in your GM vehicle? Flickering lights, power windows and locks that have a mind of their own, or a security light that prevents your truck from starting can all point to one culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM goes bad, it can create a cascade of baffling issues. This isn’t just an annoyance; it’s a reliability problem that can leave you stranded. I’ve seen it countless times in the shop—a perfectly good engine that won’t start because the BCM has lost communication with the key or powertrain module.

This is your direct, reliable solution. We offer a replacement Body Control Module, part number 15116065, that arrives at your door fully programmed to your vehicle’s specific VIN. We flash it with the latest GM-approved software, ensuring all factory bugs are addressed and performance is optimized. This means no expensive trips to the dealership for programming. You get a part that’s ready for installation right out of the box, saving you significant time and money.

Is Your GM Vehicle Showing These Symptoms?

A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs attention:

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior or exterior lights flickering, staying on, or not working at all.
• ✔ The security or anti-theft light is on, causing a no-start condition.
• ✔ Horn honking unexpectedly or not working when pressed.
• ✔ Inaccurate or dead gauges on the instrument cluster.
• ✔ Communication error codes, often in the U-series (e.g., U0140 – Lost Communication With Body Control Module).
• ✔ Wipers activating on their own or not responding to the switch.

A Straightforward Guide to Your BCM Installation

Replacing the BCM is a manageable job for a confident DIYer. The key is taking your time and being gentle with the plastic trim and connectors. Remember, this module is already programmed, so you can skip the most difficult step!

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
2. Locate the Module: On most Silverado and Sierra pickups, the BCM is located under the driver’s side of the dashboard, near the steering column. For Express and Savana vans, it’s typically found behind the center dash trim.
3. Access the BCM: You may need to remove lower dash panels or trim pieces to gain clear access. A simple set of trim removal tools will prevent scratches and broken clips.
4. 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.
5. Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
6. Final Steps & Relearns: Reassemble your dashboard trim, reconnect the battery, and start the vehicle. Note that some vehicles may require post-installation procedures as outlined below.

Important Post-Installation Information

While this 2003-2007 GM BCM is a plug-and-play part, GM’s complex systems sometimes require a final handshake between modules. Be aware of the following potential procedures, which may require a bidirectional scan tool:

• ✔ Airbag System Sync: If your airbag light illuminates after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag module.
• ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and stability control function.
• ✔ No Core Charge: We make it simple. There is no core charge for this part, so you can keep your original module without any hassle.

Disclaimer: Always consult a factory service manual for your specific vehicle for detailed instructions. If you are not comfortable performing these steps, we recommend seeking a qualified professional mechanic.
