Restore Full Functionality to Your GM Truck
Are you battling a storm of electrical problems in your GMC Sierra, Chevy Silverado, or Tahoe? When your power windows refuse to budge, the HVAC system has a mind of its own, or your dashboard lights up with random warnings, the root cause is often a failing Body Control Module (BCM). This isn’t just an annoyance; it’s a critical failure that can affect your vehicle’s safety and reliability. This OEM-quality Body Control Module, part number 22860591, is the definitive solution for your 2013 Sierra 2500 BCM and a wide range of other 2007-2013 GM trucks and SUVs.
What sets our service apart is the included professional cloning. We transfer the essential data from your original BCM directly to this replacement unit. This means no expensive trips to the dealership for programming, no complex setup procedures, and no compatibility headaches. It arrives at your door ready for a true plug-and-play installation, restoring your vehicle’s systems to perfect working order.
A Technician’s Notebook
I remember a 2011 Silverado 2500 that came into the shop with a classic case of BCM failure. The owner was frustrated because the A/C would only work on high, the driver’s side power lock was dead, and he had an intermittent airbag light. He’d already replaced a window motor to no avail. After a quick scan, we saw a handful of communication codes and the tell-tale DTC B1001. Instead of just selling him a new module, we first checked the main BCM ground under the dash—a common weak point. It was solid. The diagnosis was clear: the BCM itself had internal faults. By providing a cloned module, we had him back on the road in under an hour, all systems working, without the 3-hour wait and $200 programming fee the local dealer quoted him.
Is Your Truck 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 module needs replacement:
- ✔ Intermittent or non-functional HVAC controls, including a blower motor that won’t turn on or off.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Erratic power accessories like windows that won’t go up or down, door locks that don’t respond, or interior/exterior lights that flicker or fail.
- ✔ Security system malfunctions, leading to no-start conditions or random alarm activation.
- ✔ A cluster of seemingly unrelated electrical issues that defy simple diagnosis.
Your 5-Minute Installation Guide
Getting your truck back to normal is easier than you think. This replacement 2013 Sierra 2500 BCM is designed for a straightforward swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the Module: The BCM is typically found under the driver’s side dashboard, near the steering column. It’s a black box with several large electrical connectors.
- Swap the Units: Carefully unplug the wiring harnesses from your old BCM. Remove any retaining screws or clips holding it in place. Install the new module, secure it, and firmly reconnect all wiring harnesses.
- Reconnect and Test: Reconnect the battery terminal. Start your vehicle and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
- Post-Install Check: In some cases, an airbag light may persist. This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” function. Similarly, a “Brake Pedal Position Relearn” might be needed. These are simple procedures for any competent shop if required.

Frequently Asked Questions
What exactly is a Cloning Service?
Cloning is a service where we transfer the specific vehicle data—including VIN, mileage, and key information—from your original faulty BCM to the replacement unit. This makes the new module a perfect digital match for your truck, eliminating the need for dealership programming.
Do I need any special tools for installation?
For the physical swap, you’ll likely only need basic hand tools like a socket or screwdriver to access the module under the dash. However, if post-install procedures like an airbag sync are needed, a professional bi-directional scan tool is required.
What if my airbag light stays on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop can perform the “Setup SDM Primary Key in BCM” procedure in a few minutes to resolve this.
Do I have to send my old part back? Is there a core charge?
We require your original module to perform the cloning service. However, there is no core charge, and we always return your original module to you along with the newly programmed replacement unit.
How do I know if the BCM is really the problem?
While the symptoms listed are strong indicators, the best way to be 100% certain is with a professional diagnosis using a high-end scan tool that can communicate with the BCM and check for specific trouble codes and data stream issues.
