Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical problems in your Chevrolet Equinox, Pontiac Torrent, or other compatible GM model? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent symptoms. This replacement BCM, part number 20921436, is the reliable, cost-effective solution to get your vehicle back in perfect working order.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or anti-theft light is on, preventing the car from starting.
- ✔ Inconsistent or dead instrument cluster gauges.
- ✔ Communication errors with diagnostic scan tools (U-codes).
- ✔ Wipers or radio turning on and off by themselves.

Important Post-Installation Steps
While this module is programmed for your VIN, some vehicle systems may require a simple relearn procedure after installation to ensure full functionality. These can often be performed with a high-level diagnostic tool.
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure your brake lights and traction control system function correctly.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
