The module manages fan activation so the engine cooling fan engages when coolant temperature or A\/C demand requires airflow. It is the piece to reach for when the fan stops cycling or runs constantly.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid-state switching for smooth, repeatable fan activation\u003c\/li\u003e\n\u003cli\u003eSealed housing guards internal electronics from heat and moisture\u003c\/li\u003e\n\u003cli\u003eFactory-style connector layout for direct plug-in replacement\u003c\/li\u003e\n\u003cli\u003eRated to handle the current draw of the cooling fan circuit\u003c\/li\u003e\n\u003cli\u003eCompact footprint matches the original mounting point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Ford\u003c\/li\u003e\n\u003cli\u003efor Lincoln\u003c\/li\u003e\n\u003cli\u003efor Mercury\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eResolving an engine cooling fan that never turns on and lets temperature climb\u003c\/li\u003e\n\u003cli\u003eFixing a fan that stays on full time and drains the battery\u003c\/li\u003e\n\u003cli\u003eReplacing a relay module that has overheated or corroded at the terminals\u003c\/li\u003e\n\u003cli\u003eCooling system service on older Ford, Lincoln, and Mercury cars\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e940002904\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCooling fan control relay module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFan power switching\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFactory-style plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How do I know the relay module is the fault and not the fan motor? \u003cstrong\u003eA:\u003c\/strong\u003e Test for power at the fan connector with the module commanded on.
