Restore Your Vehicle’s Electrical Functions
Are you battling bizarre electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows, a temperamental security system, or warning lights that come and go are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable issues. This replacement Body Control Module, part number 20839063, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We recently had a 2009 Saturn Vue in the shop with a laundry list of complaints. The radio would cut out, the driver’s side power window worked intermittently, and the key fob would randomly stop working. The owner had already replaced the battery and checked fuses with no luck. After connecting our diagnostic tool, we saw multiple communication errors pointing directly to a faulty BCM. Instead of a costly trip to the dealer for a new module and programming fees, we installed one of our pre-programmed units. The installation was straightforward, and within an hour, every single electrical gremlin was gone. The customer was thrilled to have their car back to normal without the dealership hassle.

Installation and Post-Install Notes
Installation is typically a direct replacement of the original module. However, on modern vehicles, component replacement can require system synchronization. After installing this 2008-2010 Vue Body Control Module, please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct operation of the brake lights and stability control systems.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It’s the central hub for your car’s comfort and convenience features.
How does the programming process work?
After you place your order, we will require your vehicle’s 17-digit VIN. Our technicians use this VIN to load the exact GM-certified software and calibrations for your specific vehicle onto the module before we ship it to you.
Is this part difficult to install?
The physical replacement is generally straightforward for someone with basic mechanical skills, often located under the dash. However, as noted, some post-installation electronic procedures may be required with a scan tool for full functionality.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
Will this BCM fit vehicles other than the Saturn Vue?
Yes, this module is compatible with a very wide range of GM vehicles, including the Chevy Equinox, GMC Acadia, Cadillac DTS, Chevy Impala, and many more. Please refer to our detailed fitment list to confirm compatibility with your specific make, model, and year.
My airbag light is on. Will this fix it?
If the BCM is the cause of the airbag light, this will resolve the root problem. However, after installation, the new BCM must be electronically synced with the airbag system using a diagnostic tool to turn the light off, as mentioned in the post-installation notes.
