Restore Full Electrical Function to Your Chevrolet Traverse
Is your 2009-2012 Chevy Traverse suffering from strange and unpredictable electrical problems? Issues like flickering lights, malfunctioning power windows or door locks, a faulty security system, or random warning lights on your dash are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating issues. This pre-programmed Body Control Module is the definitive solution to restore your vehicle’s functionality and get you back on the road with confidence.
From the Diagnostic Bay
We had a 2011 Traverse come into the shop with a classic case of BCM failure. The customer complained that their interior lights would stay on, draining the battery overnight, and the driver’s side power window worked only when it wanted to. After checking fuses and wiring, all signs pointed to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. The installation was straightforward, and upon connecting the battery, all the phantom electrical issues were gone. The customer was thrilled to have their vehicle back to normal without the dealership hassle and expense.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Key fob not responding or working inconsistently.
- ✔ Vehicle security system engaging randomly or not arming.
- ✔ Unexplained warning lights on the instrument cluster, such as for the airbag or traction control system.
- ✔ Radio or climate control systems behaving erratically.
- ✔ No-start conditions due to security system confusion.

While the module is largely plug-and-play, some vehicles may require a couple of simple post-installation relearn procedures for systems like the airbags or brakes, which can often be performed by a qualified local mechanic.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, door locks, interior and exterior lighting, the security system, and climate controls.
Is this BCM truly plug-and-play?
Because we program it to your vehicle’s VIN, it is as close to plug-and-play as possible. In some cases, post-installation procedures like an Airbag System Sync or Brake Pedal Position Relearn may be required. These can be done with a professional scan tool.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
My original part number isn’t 20839063, will this still work?
Yes, this module is a compatible replacement for all the part numbers listed in the description. As long as your original part number is on our list, this module will function correctly in your vehicle once programmed.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
