Fans only kick on when I run my ac. I replace my coolant sensor still nothing. I have checked the fuses. Where do i go from here?

If the vehicle is not overheating then do nothing. There is a chance that the system is controlled by the vehicle computer and the fans in some vehicles only come on when the engine is under load, like when it's actually moving. Maybe sitting stationary and not working the engine it is normal for the fans not to run.

did you get any obd codes ?? well there is a possible the power relay or ac relay is not working.

If you have two electric fans the fan on the passenger side of the vehicle is the radiator cooling fan, that fan should run when the motor gets to hot. The fan on the driver side is the ac condenser fan that fan runs only when the a/c is turned on. The only time that both fans run is if the a/c is on and the motor or coolant is above normal tempeture.

My buddy used to have a car that he wired the fans to a toggle switch in the cab. I know it sounds bad, but its cheap & will get ya by till you figure it out

REPLACE THERMOSTAT.ITS STICKING CLOSE TO KEEP COOLANT FROM CIRCULATING THROUGH ENGINE AND RADIATOR. THE FANS SHOULD COME ON WHEN VECHICLE SETTING AT A LONG IDLE.THE COOLANT TEMPERATURE SENSOR GET TO CERTAIN TEMPERATURE WHICH WILL COMPLETE CIRCUIT PCM SEND POWER TO COOLANT SENSOR THEN TO COOLANT FANS RELAYS AND FANS.IF VECHICLE OVER HEATING WHILE MOVING THERMOSTAT FAULTY.IF YOU TURN AC AND COOLANT FANS DONT RUN CHECK COOLANT FANS FUSE AND RELAY.IF COOLING FANS DONT TURN ON WITH AIR CONDITIONER ON EITHER COOLANT TEMPERATURE SENSOR FAULTY OR PCM FAULTY.IF ALL LOOKS GOOD.IF ENGINE OIL LOOKS LIKE MILK SHAKE.YOU HAVE BLOWN HEAD GASKET.

Hello,
Did you have a specific engine code requiring replacement of the Cam Position Sensor?
Did you recently replace the thermostat or run low on coolant or have some other cooling system work done? The temperature sensor can be bad, or simply have a loose wire connection. Check those. There can be air in the coolant system as well. Finally, the thermostat could be sticking and will need to be replaced.

These issues have nothing to do with the Air Conditioner. However, the AC will not cool if the car is sitting still unless the condenser fans (electric) are running. Turn on the AC and check to ensure the cooling fans energize.

Most of these items you can check yourself, however if not, then have your mechanic or a mechanically inclined family member or friend check them for you.

Best regards,

have you changed the thermostat? is your fan kicking on? if your fan is not kicking on you need a temperature sensor.

Do this test with the key in run but engine off unplug the ECT (engine coolant temp.) sensor, if the fans turn on (does this by default) the system is ok, if not then check the Fan relay. Also look for burning of the electrical connections to the cooling fans.

Thats not too weird as the car would kick on the fans at full speed when it detects a problem with the sensor. Your ECU is not reading the sensor properly and needs to be checked by Ford. I hope this helps you.

the cooling fans are run by a relay it's located in the junction box. check this. there is also a thermoatic sensor located near the fans next to radiator. the fans should free spin when the engine is off this is a good indiacator that it's not the fan themselves. if the relay checks out(run engine and switch the fan relay with the a/c clutch relay when the engine reaches 180 degrees you will feel the upper radiator hose get hot the fans will turn on a short time later iof they don't it's the temp sensor near the radiator if they do it's a bad relay...please rate this thanks
