Are you battling bizarre and frustrating electrical problems in your Saturn Vue or other GM vehicle? A failing Body Control Module (BCM) is often the culprit behind a host of seemingly unrelated issues. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from power windows and locks to interior lighting and the security system. When it fails, it can make your vehicle feel unpredictable and unreliable.
This is a direct replacement Body Control Module, part number 20935349, that arrives fully programmed to your vehicle’s specific VIN. We handle the complex programming for you, loading the latest GM software updates before it ships. This means you can avoid a costly trip to the dealership for programming, saving you time and money. Simply provide your VIN during checkout, and we’ll deliver a part that’s ready for installation.
From the Diagnostic Bay
We had a 2009 Saturn Vue come in with a laundry list of complaints. The radio would turn on and off by itself, the driver’s side power window worked intermittently, and the anti-theft light would flash randomly, sometimes preventing the car from starting. The owner had already replaced the battery and checked all the fuses. A scan revealed multiple communication errors between modules. We traced the network failure back to the BCM. After installing a VIN-programmed module like this one, every single electrical gremlin vanished. It’s a perfect example of how one central component can cause widespread chaos.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the dashboard gauges or warning lights (like the security or airbag light).
- ✔ Interior or exterior lights that stay on or won’t turn on at all.
- ✔ Problems with the remote keyless entry system.
- ✔ Vehicle failing to start due to a security system fault.
- ✔ Communication errors when scanning the vehicle with a diagnostic tool.

Installation and Post-Install Procedures
Installation involves disconnecting the battery and swapping the old module with this new one. While it is designed to be plug-and-play, some vehicle systems may require a relearn procedure to sync with the new BCM. This is a normal part of the repair process.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure proper brake light and traction control operation.
There is no core charge for this module. You can keep your original part.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it. It arrives ready for installation, saving you a trip to the dealership.
How do I provide my vehicle’s VIN?
You can add your 17-digit VIN in the notes section during checkout, or we will contact you for it after your purchase is complete. We cannot ship the part until we have your VIN.
My original part number isn’t 20935349. Will this still work?
This module replaces a long list of previous GM part numbers. Please check the comprehensive list in the description to confirm that your original part number is included.
What if the airbag light comes on after I install it?
This is a possibility and requires a ‘Setup SDM Primary Key’ procedure. This syncs the new BCM with your vehicle’s airbag system and can be performed by a repair shop with a professional-grade diagnostic tool.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the physical swap is straightforward. The module is typically located in the center dash or under the steering column. However, be prepared for the possibility of needing post-install relearn procedures as mentioned.
