Restore Your Truck’s Electrical System with a Reliable, Programmed BCM
If you’re dealing with bizarre electrical issues in your GM truck or SUV—like flickering lights, malfunctioning power windows, or a security system that has a mind of its own—you’re likely facing a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and hard-to-diagnose problems. This isn’t just an annoyance; it can affect vehicle safety and operation. This replacement BCM, part number 22846364, is the definitive solution to get your truck back to 100% functionality without the exorbitant cost and hassle of a dealership visit.
We take the guesswork and complexity out of the repair. Simply provide your vehicle’s VIN at checkout, and my team will program the module with the latest GM software specific to your truck’s configuration. It arrives at your door ready for installation, eliminating the need for expensive scan tools or programming subscriptions. This is the most direct path to fixing those electrical gremlins for good.
Case Study: A Tricky Diagnosis
I remember a 2013 Silverado 2500 that came into my shop last winter. The owner was at his wit’s end. His interior lights would stay on, the radio would randomly shut off, and the power locks worked intermittently. He had already replaced the battery and checked all the fuses. After connecting my diagnostic tool, I found a slew of communication error codes (U-codes) pointing to a network problem. Instead of a complex wiring issue, my experience pointed straight to the BCM. A failing BCM often floods the data network with corrupted signals, causing other modules to act up. We installed a pre-programmed BCM just like this one, and within an hour, every single issue was resolved. It’s a perfect example of how one component can create system-wide chaos.
Is Your Truck Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Unexplained battery drain that leaves you stranded.
- ✔ Warning lights on the dash, such as for the airbag or traction control system.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (e.g., U0140, U0155) or internal module failure.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system capacitors to discharge.
- ✔ Locate the BCM: On most of these GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ 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.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Post-Install Procedures: Start the vehicle. Check all functions. As noted in our technical information, a brake pedal position relearn or an airbag system sync may be required if you see related warning lights. This is a normal part of the process for some vehicles.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Just provide your vehicle’s 17-digit VIN during checkout, and it will arrive ready to install with the latest GM software.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that acts as the central command for your vehicle’s body electronics. It controls functions like power windows, locks, lights, security system, wipers, and more.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your old BCM.
What if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Where is this part located on my 2013 Silverado 2500?
The BCM is typically found under the driver-side dashboard, attached near the steering column. You will likely need to remove the lower knee bolster panel to access it.
Will this fix my intermittent power window issue?
While many factors can affect power windows, a failing BCM is a very common cause for intermittent or total failure of window and lock controls. This module is a primary suspect and often the correct fix for those symptoms.
