Unlike simple 2-pin on\/off fan connectors, the 4-pin connector carries both the high-current motor supply and the low-current PWM control signal. A failed connector causes the cooling fan to stop operating or to run at a fixed speed, leading to engine overheating in traffic or A\/C performance degradation at low vehicle speeds.\u003c\/p\u003e\n\n\u003ch3\u003eOEM Part Number Cross-Reference\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eOEM Number\u003c\/th\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e12191399\u003c\/td\u003e\n\u003ctd\u003eDelphi 4-pin fan motor connector (primary)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e12191387\u003c\/td\u003e\n\u003ctd\u003eDelphi 4-pin fan motor connector (alternate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003e4-Pin Circuit Function (Variable-Speed Fan Motor)\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePin\u003c\/th\u003e\n\u003cth\u003eFunction\u003c\/th\u003e\n\u003cth\u003eFailure Symptom if Open\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003ctd\u003eFan motor power supply (12V, high-current)\u003c\/td\u003e\n\u003ctd\u003eFan not operating, engine overheating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003ctd\u003eFan motor ground (high-current)\u003c\/td\u003e\n\u003ctd\u003eFan inoperative\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003ctd\u003ePWM speed control signal from ECM\u003c\/td\u003e\n\u003ctd\u003eFan runs at fixed speed or not at all\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003ctd\u003eFan speed feedback \/ tachometer signal\u003c\/td\u003e\n\u003ctd\u003eECM loses fan speed data, cooling fault\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePin Count\u003c\/td\u003e\n\u003ctd\u003e4-Pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGender\u003c\/td\u003e\n\u003ctd\u003eFemale\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing Material\u003c\/td\u003e\n\u003ctd\u003eNylon, black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSealing\u003c\/td\u003e\n\u003ctd\u003eWaterproof\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Part Numbers\u003c\/td\u003e\n\u003ctd\u003e12191399 \/ 12191387\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplications\u003c\/td\u003e\n\u003ctd\u003eVariable-speed cooling fan motor, radiator fan, condenser fan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Models\u003c\/td\u003e\n\u003ctd\u003eChevrolet Cruze \/ Malibu \/ Equinox \/ Trax; Buick Excelle GT \/ Regal \/ LaCrosse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Included\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChevrolet Cruze \/ Malibu \/ Equinox \/ Trax\u003c\/strong\u003e – Variable-speed cooling fan motor connector (Ecotec engine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuick Excelle GT \/ Regal \/ LaCrosse\u003c\/strong\u003e – Radiator and condenser fan motor connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My Chevrolet Cruze is overheating in traffic but the fan runs at highway speed — could it be the connector?\u003c\/strong\u003e\u003cbr\u003eA: Yes. A failed PWM signal pin (pin 3) on the 4-pin fan connector causes the fan to run at a fixed low speed instead of ramping up in traffic. The fan appears to work but cannot cool the engine at low vehicle speeds.
