Check the fuses that powers the fans and relay to make sure the fans have voltage when the relay energises. Also check the temp sending unit that reads the coolant temperature in the engine, it tells the fan relay to energize and turn the fans on to cool the motor down.

Radiator fan does'nt work


The radiator fan circuit also has a relay and/or temperature switch, or it could have a temperature sensor,and the PCM turns the relay on and off to actuate the fan(haven't worked on a Ford from this era in a while).Relays do contain moving parts,so this is most likely the cause(use a test light to see if the relay is getting 12v,ground,a switched signal source,and that there is continuity to the fan connector).

Check the engine main relay, the radiator fan relay no. 1, 30A CDS and FAN fuses, and the ECT (engine coolant temperature) sensor for proper function. For the ECT, there should be continuity when the engine is cold (200F).

Fan has stopped working causing over heating, what is the most likely cause


There are 3 possible things;
The fan motor itself
The coolant temperature switch, which operates the fans, usually screwed into the engine block near the thermostat housing. Have to drian radiator to change it.
The relay-- It's a small black square shaped object, some are located in the fuse box in the engine compartment, and some are mounted on a bracket on the firewall, passenger side.
Could be in the wiring that connects these components.
To check the fan motor----- disconnect the wire plug from the fan motor, use jumper wires directly from the battery to the connector on the fan, If the fan works, then either the temp switch is bad, the relay, or the wiring.If the doesn't work, that is bad and needs to be replaced.

Fan


You have to check the main relay fan fuse relay and disconnect the fan and try it directly to make sure the fan motor is fine if all this is well into the cavity where the thermostat is a thermal switch that sends it relay the signal to the fan you can disconnect and the fan has to start working if this works the problem is you have the thermal switch.

AC/heating fans don't work

Blower working on top 2 settings but no air comeing from vents


Hi

Thanks for using FixYa. The possible causes due to which the blower is not working normally are fuse, blower resistor or a bad blower motor. Test the voltage at the blower with a test light. Please check the motor relay switch fuse under the dashboard. Use a multi meter to measure ohms for continuity. If these are fine, bypass the blower motor relay switch to make sure blower motor is running fine. Motor relay switch is right next to radiator fan relay switch under the hood. Pull out the blower motor relay switch to see 4 female pin holes. Test the relay switch using a 12 volts power source and a multi meter to measure continuity. If fan works after jumping the pin holes, then blower motor is fine but relay switch may be faulty. You may also need to replace the blower motor resistor. If still the problem persists, then you need to replace the blower motor.

Please do rate the solution and revert for further assistance.


Thanks
Rylee

Condensor fan motor inop - fuse good but replaced anyway - replaced relay. put 12 volts to motor and it worked. what activates the relay to send power to the motor ????


Either radiator fan switch or AC system fan activate relay. Check fan switch or look for AC fan motor fuse. Wiring diagram would help.

do they turn on with ac ?if not look for ac fan relays and check and high side ac switch in line ,if fans dont turn on for just the engine general cooling ,without ac on then check coolant temp sensor/replace it to see if it fixes it PASS THIS SWITCH IT WILL SHORT OUT COMPUTER IF U DO

A/c not working think fan isn't coming on.


Yes with airflow it work (on the interstate) but with no airflow to get rid of the A/C heat causes engine to overheat. Let's look at two possible things...first the A/C condenser fan by the radiator & then the A/C water temp switch.

IN ORDER:
Check the 30amp CDS FAN fuse (replace if blown) if it is OK then replace the the Fan#3 RELAY (which turns on the A/C condenser fan)...Then if needed replace Fan#2 RELAY (which can also control the A/C fan speed).

The Fan#2 relay can wear out and cause the type of problem your having
