A faulty impeller in 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 also result in motor seizure, causing the pump to blow a 20A fuse and stop working.
