Restore Full Functionality to Your Vehicle’s Electronics
Are you battling a storm of bizarre electrical issues in your car? Intermittent power windows, a security system with a mind of its own, or dashboard lights that flicker for no reason are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated problems. This replacement Body Control Module, part number 20935349, is the definitive solution to restore your vehicle’s electrical systems to factory-perfect condition.
The biggest hurdle in replacing a BCM is the need for expensive dealership programming. We eliminate that step entirely. Before we ship your order, we will program this module with the latest GM software updates, specifically matched to your vehicle’s 17-digit VIN. This means it arrives at your door ready for a straightforward, plug-and-play installation, saving you time, money, and hassle.
Symptoms of a Failing 2010 STS Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that don’t work correctly or stay on.
- ✔ Malfunctioning security system or constant false alarms.
- ✔ Key fob is unresponsive or works intermittently.
- ✔ Unexplained warning lights on the instrument cluster (Airbag, ABS, etc.).
- ✔ Radio, climate control, or other interior accessories behaving unpredictably.
- ✔ Vehicle failing to start due to security system immobilization.
Installation and Post-Install Notes
Because this module is pre-programmed for your specific vehicle, the physical installation is typically plug-and-play. However, in some vehicles, certain safety systems may require a quick relearn procedure after the new BCM is installed. For example, if the airbag warning light appears, a professional scan tool may be needed to perform the “Setup SDM Primary Key in BCM” procedure. Similarly, a “Brake Pedal Position Relearn” might be necessary to ensure perfect brake light and traction control operation. These are standard procedures for this type of repair and are generally simple for any qualified technician to perform.
