I have a 2002 Lincoln town car and I just put a brand new fan in and its not coming on my car runs hot when I have it in park with the ac on


Did you check the fan relays ? There are two, cooling low relay an cooling fan high relay . The relays are turned on by the vehicles PCM - engine computer , when an input from the coolant temp. sensor indicates a certain temperature ! When you turn on your A/C the cooling fan should turn on an stay on .
Relay Box
Left center of engine compartment
Cooling Fan High Relay
In relay box
Cooling Fan Low Relay
In relay box
Do you know how to test a computer controlled relay ? Go to you tube an search relay testing . Does the temp. gauge work correctly ? I know you probably don't have a factory scan tool , but this is the where I would start , checking temp. sensor input to the PCM . An with a factory scan tool I can do bidirectional testing , see if I could turn the fans on will scan tool .

Engine cooling fan only works when ac or defrost is on


if engine at long stand still,the engine temperature will rise about 190 degrees the cooling fan suppose to automaticaly turn on when coolant temperature sensor get hot it cause its resistance decrease causing pcm to send power to coolant fan relays and cooling fans, when you turn on AC the cooling fans suppose to turn on to cool down AC CONDENSOR, IF NOT AC WONT WORK COOLING FAN COOLS DOWN REFRIGERANT SO IT CAN RECYCLE THROUGH THE SYSTEM AGAIN.your cooling is suppose to turn on when engine at a sit still if vechicle not moving as coolant temperature rises at a set point the cooling fans will turn on cool down engine.cooling fans dont turn on when you first cold stsrt vechicle unless you have AC SWITCH ON.if cooling fans dont turn on when vechicle at a long stand still or moving along slow traffic.if coolant temperature sensor been replaced and fuses and relays okay have dealership check see if pcm driver circuit working faulty pcm will cause cooling fans not to turn on.

What would cause my radiator fans not to run


A lot of different things fall into this senario.Low coolant level,air in the cooling system,and a stuck thermostat,or,a bad coolant sensor,or even a bad cooling fan relay,or the cooling fans are bad.Turn the defrost on or the ac,the cooling fans should come on if the fans,and the relay are ok,if so,replace the thermostat,and coolant sensor,and bleed the cooling system of air.

Kia over heats when air is on only


your AC cooling fan is not working properly, most vehicle has two fans, one for the radiator and another for AC, both work in sync with one another; if one cooling fan only working it does not produce enough cooling for both radiator and condenser at the same time; by running ac you producing more heat and its cant cool the engine fast enough with one fan so your engine is overheating when running AC. The temperature sensor could be faulty and need to be replace or your fan motor can also be faulty. Check the fuse first and the relay make sure they are not burn out. sensor cost about 30 bucks get it new, relay 35-40 new used 5 bucks at junk yard, fan get it from a junk yard for 25-30 bucks, new will run over 100 bucks. don't run the air and overheat your motor, it can damage your engine or may blow your radiator. if you do run ac watch the temp very closely, don't let temperature get into the red.

Replaced relay, but both electric fans won't come on


Are we talking about the cooling fans for the engine and AC condenser?? Only one cooling fan will cycle on and off during normal operation. The main cooling fan will cycle on and off as needed for cooling the engine. If you turn on the AC or select a defrost mode on your climate control then the 2nd additional fan will run usually continuously in order to condense the freon in your AC system for cooling the interior of your car and in defrost mode it helps to reduce interior moisture on the glass (defog/ defrost). If no fan comes on at any time whether the engine is hot or cold or whether you turn on the AC or not and you have already replaced a cooling fan relay and checked related fuses then either the fan /s are bad or you dont have power in or out of the fan circuit which consists of several components that would need to be checked. Let us know if you find anything else or have additional questions.

95 grand am radiator fan only runs with AC on


Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson

1992 5.0 camaro no cooling fan except with ac


Yes there is a relay, but first answer this question, do you know the fans don't come on until the engine temp is above 230+ degrees F.? That is almost in the hot zone. run a scanner on the engine and watch the ECT sensor temp reading to verify proper cooling fan operation, a quick test to see if the system works is to unplug the ECT sensor, the fans will go into failure mode and turn on to avoid damage to the engine.
