Frembrit Posted July 19, 2022 Share Posted July 19, 2022 Hi, Sorry I had a quick search but couldn't find the answer. My friend has a 2014 1.0 Ecoboost and he said the radiator fan stopped working today, is there a fan switch somewhere or is it controlled by a module please? He can spin the Fan by hand and the fuse is ok. He's an hour away from me so I can't 'pop round' so to speak. We managed to find the temp sensor on the thermostat housing but that appears to be for the temp gauge in the car. I did notice (via a video call) an electrical plug at the bottom of the radiator, would that be the fan switch or just another temp sensor for a module? Thanks.

alanfp Posted July 19, 2022 Share Posted July 19, 2022 I'm pretty sure the fan only comes on if necessary, so not on all the time, dependant on coolant temp. But on most Fords, I understand it automatically comes on if the aircon is switched on (mine certainly does). So I'd check that first.

Frembrit Posted July 19, 2022 Author Share Posted July 19, 2022 Thanks. Sorry, should have said he's done that check and it doesn't come on. His fan is usually on all the time as he has the air con on all the time, also he's a driving instructor and the engine was hot. He saw the temp gauge during a lesson and had to pull over and wait for the engine to cool before continuing, fan still wasn't working and was driving with the heating on. I've not heard from again but the last thing he was going to try was to test the fan by applying power to it. Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted July 20, 2022 Share Posted July 20, 2022 Don't think fan switches have been fitted for about 20 years now! Controlled by sensors and modules nowadays. May be controlled by the PCM rather than a separate module. The electrical connector at the bottom of the fan cowling is for a resistor (which is still the conventional type) and looks like this. That may have blown in the extreme hot weather.

Frembrit Posted July 20, 2022 Author Share Posted July 20, 2022 Thanks Tom. So much easier on old cars 😂, unplug from fan switch, bridge pins and the fan would be on. Watched a few YouTube videos showing a control module but that was on a ST. Another video showing worn out bushes on the fan motor after 96K miles (Friend has 120K on his car), so will need to hear back on how he got on with the fan test. 1 Quote Link to comment Share on other sites More sharing options...

Mine probably runs about 5% of the time. But as you say, if he can apply 12v to it directly to see if it runs, that will tell him a lot.

Frembrit Posted July 21, 2022 Author Share Posted July 21, 2022 Thanks. He managed to test it last night and it doesn't work. New fan on order. 1 Quote Link to comment Share on other sites More sharing options...
