A faulty impeller within the vacuum pump can cause vehicle performance issues. Water ingress may affect pump operation, and over time, the impeller on the motor spindle can crack or break. A damaged impeller reduces air pressure or vacuum output, impairing pump function. This can result in motor seizure, potentially causing the pump to trip a 20A fuse and shut down.
