Climate Control Haywire?

[lsherlockl]

I feel bad i always end up coming on here when I need help i should really stay around longer, but anyhow...

 

2014 FFH SE

 

I was driving home from work yesterday and it was reasonable chilly like 31 degrees Fahrenheit (sunny so black interior made it not soo bad). So after the engine came up to temp I decided to turn on the climate control (which is usually left at 68 degress at recommendation of some old post somewhere) i was suprised to hear the blowers roar at max speed out of all vents i look down and see the climate is displayed as being set to 21 degrees WTH thats even out of the range that is normally acceptable (something like 50-60 i thinK) i immediately turn off as its blowing freezing cold air everywhere try a bit further down my 1 hr commute same thing, try adjsuting VIA buttons or touch screen no luck. I wanted to power cycle it but I had all green lights and didn't want to stop.

 

So this morning rolls around i think maybe things will be better after power cycling, let the engine come up to temp and turn on climate control, this time i did it by voice thinking i could cheat around the buttons being weird. And low and behold climate turns on displays 68 degrees and proceeds to go crazy blowing cold air all over the place WTF. So i start trying to adjust temp, which now the buttons make no noise but will "increase" the temperature number if i move it up to HI it will sometimes give me heat a bit and sometimes cold. I tried several times on my drive in.

 

Any thoughts? I read some similar ish behavior with remote start things, but this seemed a bit more different.

 

Just rather ticked as not that far out of warranty and first a wheel bearing now this, quite aggravating to say the least. Specially as in WI se still will likely be getting below freezing temps for a bit yet.

I had something similar happen to me but with the A/C versus your heater. Here is my post where I describe what I did to get out of that glitch condition in my case.

thanks Ill try that tonight, I also tried resetting the MFT through the interface though I always turn off my climate control via I think the soft touch power button i think thats the power dead center in the console panel. Should also state my + and - buttons make no sound too

 

I will let you know how it goes tonight

I just wanted to make a followup post for closure. Dealership had to do a hard reset of systems using the ford computer. Still cost me ~100 bucks kinda ticked at that but at least climate control works. Also gave advice of try pulling the secondary battery (lead acid one) for 20-30 minutes if run into it again or if run into it on the road as in WI there are times when you need heat and more importantly defrost to work.

If you know haw to safely disconnect and reconnect the negative battery connection for a few minutes, that's always a cheap first try. The second is to replace the battery particularly if it's a few years old or has the red ball showing in the sight gauge.

I had a similar situation this week (Dec, 2020). The digital display of the climate control on the screen on my 2013 Ford Fusion SE went bonkers and was displaying weird temperatures (00, 03, 35, 70 and even odd symbols like question marks). I could not adjust the temperature on the screen and the manual "+" and "-" buttons below the screen weren't working either. I took the above advice and disconnected the negative battery terminal and let it sit for 30 minutes. When I reconnected the battery terminal, the problem was gone and the screen and manual buttons were working again. I guess this is similar to unplugging a router to reboot it. Worked like a charm. I was afraid that I'd lose all of my radio station pre-sets and the bluetooth connection to my phone. But surprisingly, those were not affected by disconnecting the battery! So happy with these results!

I am currently having a similar issue.  2020 Fusion with 5,000 miles.  

When on "AUTO" it will blow cold air at max unless temp is set to "HI".  Issue comes and goes but of course would not screw up for the mechanic so the dealership says they don't know what to fix.

 

Any suggestions?

Try the climate control reset.

Someone on youtube pointed out a reset for the actuators.  Press the Climate control power button and the defrost at the same time.  NOT on screen.

Yesterday, when i got into my car and started it, I noticed that my heat was turned off.  (I never power off my climate control, especially in the winter)  I go to turn it on and it seems fine.  Cold morning.  It sounds like the air is blowing on high in the defogger setting even though it is on auto. (usually at start up, you hear no sound until the car comes to temperature and starts to heat)  Now after about 15 minutes, my car is getting too hot, to the point of if I have the air coming out of the face vents, you really can not keep your hand on the heat.  I tried the actuator reset that I saw on you tube, which is nice to know, but it did not solve the problem.

 

I can not control the heat at any temperature unless I drop it down to low (my temp) where it goes cold.  as soon as I hit the temp increase button at 60, the heat fires up again and on high.  If I put the auto on at 68, it blows out the defogger.  If I go to manual control and hit the face vent, it is extremely hot.  As I lower the temp down to 60, it seems to blow higher.  Once I hit the my temp or go to low, then it goes to cool.  Now I have to drive with my side set at lo and the passenger side set at 60 to balance the hot and cold.  WTF is going on?  Any help is appreciated.  I have an appointment at the dealership for this Saturday.      Note:  I did take my 16 Fusion to the dealership this past Saturday to get a recall of the shifter cable fixed.  Afterwards, I did notice that the shifter is very stiff now as compared to prior.  I am figuring that it is something that i will nee to get used to.  (Is this correct?)  

 

I look forward to your input and getting my temp under control.
