Tired of Chasing Electrical Gremlins in Your GM Truck?

If you’re dealing with a vehicle that seems to have a mind of its own—flickering lights, a dead instrument cluster, power windows that won’t budge, or a security system that randomly prevents you from starting your engine—you’re not alone. These frustrating and seemingly unrelated issues often point to a single culprit: a failing Body Control Module (BCM).

This VIN-programmed BCM, a direct replacement for part numbers like 15263363 and 25844480, is the definitive, hassle-free solution to restore order and reliability to your truck or SUV.

We take the guesswork and dealership expense out of the equation. By providing your vehicle’s VIN during checkout, we program the module specifically for your truck. This ensures all factory settings and security information are correctly loaded, making for a true plug-and-play installation. This is the most effective way to address common issues related to a failing 2007–2011 GM BCM and get your vehicle operating as it should.

Is Your GM Truck Showing These Telltale Signs?

A failing BCM doesn’t always fail completely. It often starts with intermittent problems that can be difficult to diagnose. If your vehicle is experiencing any of the following, a faulty BCM is the likely cause:

• ✔ Intermittent or non-functional power windows, door locks, or interior lights.
• ✔ HVAC blower motor or climate controls not working correctly.
• ✔ The security or anti-theft system engages randomly, causing a no-start condition.
• ✔ An airbag warning light is illuminated, often with a DTC like B1001 (Setup SDM Primary Key in BCM).
• ✔ Erratic wiper operation or dashboard warning lights that flicker without reason.
• ✔ A host of communication codes (U-codes) stored in various modules.

A Straightforward Guide to Installation

One of the best features of our VIN-programmed BCM is the simple installation. You don’t need to be a master mechanic to get this job done right in your own driveway.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
2. Locate the BCM: On most compatible GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with several large multi-pin connectors.
3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed to be released. Once unplugged, unclip or unbolt the old BCM from its mounting bracket.
4. Install the New Module: Seat the new BCM into the mounting bracket and firmly reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, locks, windows, wipers, and HVAC to confirm proper operation.

Post-Installation Note: In some cases, particularly if the airbag light was on, a ‘Setup SDM Primary Key’ procedure may be needed using a professional scan tool to sync the new BCM with the airbag system. A ‘Brake Pedal Position Relearn’ might also be required for full functionality of the traction control system.
