ptjones Posted February 23, 2016 Report Share Posted February 23, 2016 I have been hearing a small fan noise like the bearing is going out in the MFT area and I had the electronics person at FORD listen to it. He said their are no fans in MFT and radio. He said their could be a small fan in the climate control system to monitor temp. I thought I would post this to see if anyone had any ideas. ;) Paul Quote Link to comment Share on other sites More sharing options...
jestevens Posted February 24, 2016 Report Share Posted February 24, 2016 (edited) I've never seen the parts or any circuit diagrams but I always figured that was a fan for the on board computer that controls the MFT., because it always seems to be on in my 2013 SEL whether I have "climate" turned on or off. The only other thing that gets that hot would be an amplifier or bass speaker? Does this car even have a separate subwoofer? If it does it must be under one of the seats.

plus 3 golfer Posted February 24, 2016 Report Share Posted February 24, 2016 Paul, do you hear the noise with the climate control off? The humidity and temperature sensor has a fan that should only be powered when the blower motor relay is energized. Also, you could try pulling fuse F45 which supplies power to the fan. In-Vehicle Temperature And Humidity Sensor The in-vehicle temperature and humidity sensor contains a thermistor and a sensing element which separately measures the in-vehicle air temperature and the humidity, then sends those readings to the HVAC control module to adjust the actuator doors. The in-vehicle temperature and humidity sensor has an electric fan within the sensor that draws in-vehicle air across the two sensing elements. If the vehicle cabin becomes too humid the HVAC control module adjusts the air inlet door to allow more fresh air. When the humidity level drops, it adjusts back to recirculated air. scottwood2 and ptjones 2 Quote Link to comment Share on other sites More sharing options...

This fan runs all the time and pulling fuses would isolate witch circuit it is on. When I get a chance I will look at the service manual to see what's in the console. ;) Paul Quote Link to comment Share on other sites More sharing options...
ptjones Posted March 10, 2016 Author Report Share Posted March 10, 2016 My Dealer figured out what the noise is and has ordered part. It is the inverter for the 120VAC outlet apparently has fan in it. :) Paul Quote Link to comment Share on other sites More sharing options...
RobMax Posted March 27, 2016 Report Share Posted March 27, 2016 A front seat power outlet? I take it that's an SEL option.Was there something plugged into that outlet? If not, interesting there would be a fan turned on to cool it. Quote Link to comment Share on other sites More sharing options...

They have the part, but need time to install it. I will try to take a pic of it when I get it replaced. :) Paul Quote Link to comment Share on other sites More sharing options...

I figured since you thought it was the MFT that the fan noise was up front in the dash. So is the fan located in the console somewhere near the outlet then?

It's a pain trying to figure out where noises come from, right?You should've seen me this weekend banging the dash near my radio controls with my head against it trying to figure out where the rattle was. I finally found it and was able to fix it thanks to a youtube video showing how to take everything apart in order. ptjones 1 Quote Link to comment Share on other sites More sharing options...

ptjones Posted March 31, 2016 Author Report Share Posted March 31, 2016 (edited) Here is a pic of CMAX 12v to 110vac inverter that was making fan noise. Unfortunately the new inverter started out making more noise than my old one. One of the fan blades was hitting something and almost stopping, but after a few starts it wore down so it isn't making as much noise, still not right. To make sure I listened to a new Fusion Hybrid and it didn't make any noise so FORD ordered another new one. ;) Paul Edited April 1, 2016 by ptjones Quote Link to comment Share on other sites More sharing options...

ptjones Posted April 1, 2016 Author Report Share Posted April 1, 2016 I decided to remove the fuse to make the sound go away. It turns out there are two fuses F24 and F32 and I took them out separately and the fan noise didn't go away. Darn! ;) Back to square one. :sad: :headscratch: :shrug: Paul Quote Link to comment Share on other sites More sharing options...

ptjones Posted April 2, 2016 Author Report Share Posted April 2, 2016 Rear Junction Box not front?That's right, rear drivers side, just for grins I'm going to take both fuses out at the same time to see what happens. then I'm going to try climate control fuses. ;) Paul Quote Link to comment Share on other sites More sharing options...
ptjones Posted April 3, 2016 Author Report Share Posted April 3, 2016 Well I figured what system the noise is coming from, "Heating control head (manual A/C), Climate control module" OM page 273 fuse #71 10 Amp. under glove box. So I'll talk to Dealer tomorrow to see if they can figure out what to do. ;) Quote Link to comment Share on other sites More sharing options...
ptjones Posted April 5, 2016 Author Report Share Posted April 5, 2016 Took MADMAX in today and they ordered Climate temp sensor module which includes fan, should have tomorrow. :) Paul Quote Link to comment Share on other sites More sharing options...
RobMax Posted April 5, 2016 Report Share Posted April 5, 2016 Well at least it's in the area of the MFT so your ears aren't too bad. :)Good job of troubleshooting and diagnosing the issue. I wonder if this will be a common issue going forward for owners. Let us know what the part # and normal part cost is if you can get it. ptjones 1 Quote Link to comment Share on other sites More sharing options...

ptjones Posted April 21, 2016 Author Report Share Posted April 21, 2016 Got problem fixed and it wasn't what I thought, here is the problem: Temperature Control Sensor Part Number: 19C734(YH-1815)The temperature control sensor has a little fan in it. ;) Paul RobMax 1 Quote Link to comment Share on other sites More sharing options...
RobMax Posted April 21, 2016 Report Share Posted April 21, 2016 Nice, thanks for the part #. Google shows it goes in a few different Fords so hopefully the Rock Autos of the world will carry them cheaper than the stealerships will. ptjones 1 Quote Link to comment Share on other sites More sharing options...
ptjones Posted April 21, 2016 Author Report Share Posted April 21, 2016 Here's the pic: it's only an inch in diameter and maybe 4"'s long, so fan and temp sensor are inside. :) Paul Quote Link to comment Share on other sites More sharing options...
