• Function & Symptoms: Relay No. 219 is commonly used for cooling-fan control in the engine-compartment fuse/relay box (fan may run-on after shutdown on some vehicles). A faulty relay may cause radiator/condensor fans stuck ON (battery drain) or not turning ON (overheating / weak A/C). Catalogs note relay function can vary by vehicle—on some applications it serves as a main accessory-power / fuel-pump relay. Install: disconnect battery, locate the engine-bay relay carrier, pull the relay straight up, then press-fit the new relay fully into the 5-pin socket.
