Are you chasing electrical gremlins in your GM truck? Flickering lights, a moody key fob, power windows with a mind of their own, or a dashboard that lights up with random warnings can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your truck’s comfort and security features, a faulty BCM can make your reliable workhorse feel unpredictable. This isn’t just an annoyance; it’s a breakdown of your vehicle’s core functions.
This is a direct-fit replacement Body Control Module, compatible with part numbers 22737275, 22846365, and 22846364. We take the guesswork and dealership hassle out of the repair. Simply provide us with your vehicle’s VIN after your purchase, and our technicians will program the module with the latest GM software specifically for your truck. This means you get a part that’s ready to be installed right out of the box, restoring the seamless operation you depend on.
A Technician’s Notebook
I remember a 2013 Silverado 2500 that came into the shop with a classic case of BCM failure. The owner was frustrated because his dome lights wouldn’t turn off, draining the battery overnight, and the radio would randomly shut off. He’d already replaced the battery twice. We scanned it and pulled a U0140 (Lost Communication with Body Control Module). Instead of a complicated and expensive rewiring job, we started with the most likely cause. Swapping in a VIN-programmed BCM like this one solved every single issue in under an hour. It’s a perfect example of how targeting the vehicle’s electronic ‘brain’ can fix a dozen seemingly unrelated problems at once.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution for your Silverado 2500 BCM issues:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ Key fob not responding or intermittent remote start failure.
- ✔ False ‘Service Theft Deterrent System’ or ‘Service Airbag’ warnings.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes.
- ✔ Instrument cluster gauges behaving erratically or going dark.
A Straightforward Guide to Your BCM Installation
Replacing the BCM is a job most DIYers can handle with basic tools. It’s typically located under the driver’s side of the dashboard, near the steering column. Follow these steps for a smooth installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- Access the Module: Remove any lower dash panels or knee bolsters needed to gain clear access to the BCM. It’s often mounted to a bracket with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely reconnect all the electrical connectors, ensuring they click into place.
- Final Steps & Relearns: Reinstall the dash panels and reconnect the negative battery terminal. Start the vehicle. Note that some models may require a post-installation procedure like a Brake Pedal Position Relearn or an Airbag System Sync if a warning light appears.
