How it works: A relay is an electrically operated switch. A small control current energizes the relay, which then opens or closes the contacts that carry current for the circuit it serves. This lets a low-current switch or module control that circuit.
Signs this part may need replacing: The component the relay controls does not turn on, works only intermittently, or stays on when it should shut off. Fuses, wiring, switches and control modules can cause the same symptoms, so diagnose the circuit before replacing the relay. If a failed relay is the cause, this unit replaces it.
