LostInTennessee Posted September 17, 2020 Report Share Posted September 17, 2020 (edited) 2015 SEL 2.0L Turbo 117,000 miles This has happen twice, the first time the radiator fan continued to run at high speed after the engine was turned off and ran the battery down, had to jump off. Car was ok, i.e. problem didn't return. Then yesterday the same thing happened and I disconnected the battery and the fan whet off, but connecting the battery again starter the fan running. Left the battery disconnected over night and reconnected the battery in the morning and the fan DID NOT START. . Checked the relayes (32,38,39) and they seemed to be OK. After several trips today, still seemed to be OK. I will pull the relays one at a time to see which one is closed. Any suggestions?

WWWPerfA_ZN0W Posted September 17, 2020 Report Share Posted September 17, 2020 First time I have heard of this issue on a similar vehicle. But usually means the fan control module has failed, and it is time to replace the fan assembly. May be a short in the fan motor as well. Is the fan noisy? There is an SSM for this: https://drive.google.com/file/d/1G2gSkgUSAREfsUgoYPasDAuitNEkvnZX/view?usp=sharing A failing battery MAY cause this as well, but I don't see how. Worth a check tho. Your disconnection of the battery overnight also a) reset the pcm, and b) allowed the pcm to relearn the battery. Quote Link to comment Share on other sites More sharing options...

If you're suspecting relays, it won't be closed all the time as the issue is intermittent. You could try to swap the relay with another one of the same rating and see if the issue changes. 1 Quote Link to comment Share on other sites More sharing options...
LostInTennessee Posted September 18, 2020 Author Report Share Posted September 18, 2020 I will swap relats today, I think I have some out of wrecks. (problem has not returned). Quote Link to comment Share on other sites More sharing options...
LostInTennessee Posted September 29, 2020 Author Report Share Posted September 29, 2020 Solved (maybe) When it happened again, I felt each relay (32,38, and 39) and all where warm BUT relay 39 was hot. I removed 39 (fan stopped) and moved the relay in 38 to the 39 slot and the fan stayed OFF. Replaced the bad relay with a new one and all is well (so far - 6 day ago). 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 30, 2020 Report Share Posted September 30, 2020 Nice work. But remember, the relay may be a symptom of the fan/module having a problem. Fingers crossed the relay is a longterm fix tho Quote Link to comment Share on other sites More sharing options...
LostInTennessee Posted November 11, 2020 Author Report Share Posted November 11, 2020 Ok, so it is not fixed or a different problem has arisen. For a couple of months or so all was OK. Then it started to overheat. Quick look under the hood showed neither fan was running. Relays (32, 38, 39) seemed to be OK (not 100% tested). ' Note: pins 3 is output on relay location #3 and 5 output relay location #1. Fan controller relay #3, has 0V at pin 5, this suggest that fuse F59 is open. But 12V from the battery to pin 5 turns on fan motor #2 so motor is OK On fan controller relay #1, pin 3 has 12V, AND when 12V from the battery is jump to pin 5on relay #1 the fan does not run suggesting fan motor is bad. Fuse F59 is located under the fuse/relay box. Looking at owners manual, it says to release the two latches, located on both sides of the fuse box. I can find the one on the left (standing on the driver side) but not the right side. Where is the right hand latch ??? Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted January 17, 2022 Report Share Posted January 17, 2022 have you checked the fan relays? Quote Link to comment Share on other sites More sharing options...
Tar Heel Posted March 21, 2023 Report Share Posted March 21, 2023 I am having this same issue with my 2015 Ford Edge Titanium. I am a woman who has no knowledge or the ability to work on cars. Did you ever determine the issue with the fan and how to fix it? I would like to go to a repair shop with a little knowledge of the situation. Thanks!
