Are you chasing down electrical gremlins in your GM vehicle? One minute the power windows work, the next they don’t. Maybe your interior lights are flickering, the radio is acting possessed, or worse, you’re dealing with a frustrating no-start condition because the security system won’t recognize your key. As a technician with over two decades of experience, I’ve seen these exact symptoms hundreds of times, and they almost always point to a failing Body Control Module (BCM).
The BCM is the central command center for your vehicle’s body electronics. When it starts to fail, it can create a cascade of bizarre and unpredictable problems. This isn’t just an annoyance; it can be a serious issue affecting vehicle security and function. Instead of spending a fortune at the dealership for diagnostics and programming fees, we offer a direct, reliable solution. This is a genuine GM Body Control Module, part number 22820314 (also replaces 22915542), that arrives at your door fully programmed and ready for installation.
We take the guesswork and hassle out of the repair. Simply provide us with your vehicle’s VIN during checkout, and our experts will flash the module with the latest, most stable software direct from GM, ensuring it’s a perfect match for your specific vehicle’s options. This is the most effective way to restore your vehicle’s electronics to perfect working order.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Chevy Traverse. The complaint was intermittent: the liftgate wouldn’t open, the dome lights would stay on, and occasionally the dash would light up with random warnings. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a slew of U-codes (U0140, U0155) indicating a loss of communication with the BCM. Instead of a complex wiring issue, the root cause was an internally failing Programmed GM BCM. Swapping in a VIN-matched module like this one cleared all the codes and restored every single function in under an hour. It’s a common failure, and this is the definitive fix.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security or anti-theft system preventing the engine from starting.
- ✔ Unresponsive key fob or remote start functions.
- ✔ False warnings on the instrument cluster (e.g., “Service Airbag,” “Service StabiliTrak”).
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0141, or other U-codes.
- ✔ Inconsistent operation of the radio or climate controls.
Your Straightforward BCM Installation Guide
Installing your new Programmed GM BCM is a manageable job for a confident DIYer or any professional mechanic. With our pre-programming service, you skip the most complicated step. No core charge means you can keep your old part!
- 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.
- Locate the BCM: On most of these models (like the Traverse, Acadia, Enclave, and Impala), the BCM is located on the driver’s side of the dashboard, often behind the lower dash panel near the steering column. For Savana and Express vans, it’s typically found in the center dash area.
- Remove Connectors: Carefully disconnect all electrical connectors from the old BCM. They have locking tabs that need to be pressed or lifted. Do not force them. Note their orientation.
- Swap the Module: Unbolt or unclip the old BCM and remove it. Mount the new module securely in its place.
- Reconnect Everything: Plug all the electrical connectors firmly into your new BCM. Reconnect the negative battery terminal.
- Perform Post-Install Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc. In some cases, additional steps may be needed. If the airbag light is on, an “Airbag System Sync” (Setup SDM Primary Key) is required using a pro-level scan tool. A “Brake Pedal Position Relearn” might also be necessary for proper brake light and traction control operation.
Disclaimer: Procedures can vary. Always consult a factory service manual for your specific vehicle if you are unsure.
