Before condemning your BCM, always inspect the main ground connections, especially the one located on the driver’s side frame rail below the door. A corroded or loose ground can mimic BCM failure and cause recurring electrical issues even after a new module is installed. Cleaning and securing this ground is a crucial first step in any BCM-related diagnosis.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC controls not working or the blower motor operating intermittently.
- ✔ An illuminated airbag warning light, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, leading to no-start conditions or random stalling.
- ✔ A variety of communication errors or body-related DTCs stored in the vehicle’s memory.
- ✔ Wipers or radio behaving erratically without user input.
