2008-2012 Express 2500 Van BCM 20935349 | Cloning Service

Restore Full Functionality to Your GM Vehicle

If you’re dealing with bizarre electrical problems in your 2008-2012 Express 2500 Van—like power windows with a mind of their own, flickering dash lights, or a security system that prevents the engine from starting—a failing Body Control Module (BCM) is the likely culprit. As the central nervous system for your vehicle’s electronics, a faulty BCM can turn a reliable workhorse into a source of constant frustration. This isn’t just an inconvenience; it can affect vehicle security, safety systems, and your ability to get the job done.

We offer a straightforward and reliable solution. This listing is for a replacement Body Control Module that includes our professional cloning service. This means we transfer the exact data from your original BCM to this replacement unit. The result? A true plug-and-play fix that eliminates the need for expensive and time-consuming dealership programming. We flash the module with the latest GM software updates using your VIN, ensuring optimal performance and compatibility.

Is Your Vehicle Showing These Symptoms?

• ✔ Intermittent or non-functional power windows, locks, or mirrors.
• ✔ Erratic interior or exterior lighting (flickering, staying on, or not working at all).
• ✔ The security or anti-theft system light is on, preventing the engine from cranking.
• ✔ Inconsistent or non-working radio and climate controls.
• ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0100, or B1001.
• ✔ A battery that drains overnight with no obvious cause.
• ✔ Horn honking unexpectedly or not working when pressed.

Your Straightforward BCM Installation Guide

Installing your cloned 2008-2012 Express 2500 BCM is a manageable job for a DIYer with basic tools. Following these steps will ensure a smooth process.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts. Wait a few minutes for the system capacitors to discharge.
2. Locate the BCM: In most Express and Savana vans, the BCM is located in the center dash area, often accessible by removing lower dash panels or the glove box. Consult a vehicle-specific guide for the exact location.
3. 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 and remove it from the vehicle.
4. Install the New Module: Mount the replacement BCM onto the bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
5. Reconnect Power: Re-attach the negative battery terminal and tighten it securely.
6. Test Functionality: Turn the key to the ‘On’ position and test all body functions: lights, windows, locks, radio, etc. Start the vehicle to ensure it runs correctly.
7. Perform Relearns (If Needed): As noted in our post-installation procedures, you may need a scan tool for an airbag system sync or a brake pedal position relearn if any warning lights appear.
