Chevrolet G30 heater fan stopped working after hitting a bump, fuse checked on Chevrolet G30

Some Chevrolet G30 owners report experiencing issues with the heater fan not working after hitting a bump, which may stem from electrical, mechanical, or coolant-related problems. Many owners find it essential to check the fuse associated with the heater fan to ensure it is not burnt out or damaged. Additionally, hitting a bump can sometimes jostle loose connections, prompting owners to inspect the wiring and connections to the heater fan for security. If the fuse is intact and connections are secure, the blower motor itself may need inspection or replacement. Furthermore, some owners notice that the fan may only work intermittently or at low power, suggesting a potential issue with the blower motor drawing too much power, warranting further investigation. It is recommended to systematically check these components to effectively diagnose and resolve the heater fan issue.
