Function and Common Failure Modes: The relay controls one or more cooling fans and their operating stages, ensuring fans engage at the right temperatures. Relays typically fail due to heat and vibration, corroded or worn contacts, moisture ingress, or electrical surges. Symptoms of failure include fans not running, fans stuck on, intermittent fan operation, or engine overheating. Lifespan varies by vehicle use and environment; inspect the relay whenever cooling issues or related fault codes appear.
Replacement Guidance: Basic mechanical skills and common hand tools are sufficient for installation. Recommended steps: disconnect the vehicle battery for safety, locate the relay inside the engine bay fuse/relay box or near the radiator, unplug the connector and any attached wiring harness, remove mounting fasteners, install the new relay and harness, reconnect electrical plugs and battery, then verify fan operation and check for fault codes. Take care to inspect connector pins and replace damaged fuses if necessary.
