Restore Full Functionality to Your GM Vehicle
Are you dealing with a cascade of bizarre electrical problems in your truck or car? Flickering lights, power windows with a mind of their own, intermittent starting issues, or random warning lights on the dash are classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can turn a reliable vehicle into a frustrating puzzle. This isn’t just an annoyance; it can affect safety systems and leave you stranded. This professionally programmed BCM, compatible with part numbers like 13594692 and 13580690, is the definitive solution to get your vehicle operating correctly again.
We’ve streamlined the repair process to eliminate the most expensive and time-consuming step: dealership programming. Our service is simple: after your purchase, you’ll ship your original BCM to us. We will then transfer all the critical data—including your vehicle’s specific VIN, security information, and option configuration—to this replacement unit. The result is a true plug-and-play module, ready for installation right out of the box, saving you hundreds of dollars and days of vehicle downtime.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security system preventing the engine from starting (blinking security light).
- ✔ Horn honking randomly or the alarm system malfunctioning.
- ✔ Inconsistent operation of the radio, climate controls, or dashboard gauges.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication loss with other modules (e.g., U0140, U0155) or internal BCM failure.
- ✔ Headlights or tail lights staying on and draining the battery.
A Technician’s Notebook: The Haunted Silverado
I had a 2015 Silverado 2500 in my bay that the owner swore was haunted. The dome lights would fade on and off while driving, the driver’s window would only work occasionally, and twice it refused to start, just a click and a flashing security icon. He’d already replaced the battery and checked the grounds. After hooking up my scan tool, I saw a dozen communication loss codes pointing to the BCM. Instead of a costly new module and a tow to the dealer for programming, we used this exact cloning service. I pulled his old BCM, shipped it out, and got the programmed replacement back in a few days. After a 15-minute install, every single electrical gremlin was gone. It’s a testament to how a single module failure can create widespread, confusing symptoms.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most GM trucks and SUVs like the Sierra and Tahoe, the BCM is located under the driver’s side of the dashboard, often near the steering column or against the firewall. On sedans like the CTS or Impala, it may be in the dash or a hinge pillar. A quick search for your specific model will confirm the location.
- ✔ Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be pressed to release. Once unplugged, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount your pre-programmed replacement BCM in the same location and securely reconnect all the electrical harnesses. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, locks, windows, radio, etc., to confirm the repair.
Important Post-Installation Information
While this 2015 Sierra 3500 BCM is delivered ready for installation, some vehicle systems may require a ‘handshake’ with the new module. Depending on your specific model, you may need a professional scan tool to perform a ‘Brake Pedal Position Relearn’ or, if the airbag light appears, an ‘SDM Primary Key Setup’. These are simple procedures for any qualified technician. There is no core charge for this part; you can keep your original module.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide instructions for shipping your original BCM to us. We then extract the unique data from your module and flash it onto the replacement unit. This ensures it works perfectly with your vehicle’s existing keys, security system, and features. We then ship the programmed module back to you.
Is this a plug-and-play part?
Yes, because we clone the data from your original module, this BCM is designed to be plug-and-play. No additional programming at a dealership is required for the module itself. Some minor system relearns, like for the brake pedal sensor, may be needed after installation.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which we will transfer during the cloning process.
What if my part number is slightly different?
This module replaces several part numbers, including 13594692, 13594768, 13593214, and 13580690. As long as your part number is on our compatibility list, this module will work for you.
Will this fix my ‘Service Airbag’ light?
If the airbag light is caused by a communication fault with the BCM, this will resolve it. However, after installation, the new BCM may need to be synced with the airbag system (SDM) using a scan tool. This is a standard procedure called ‘Setup SDM Primary Key in BCM’.
Is there a core charge?
No, there is no core charge. You are not required to return your original module after the cloning service is complete.
