I've been wondering if the HVAC system fails from time to time. All winter I had the A/C off and tied to run the heater and defroster often. The heater usually works for a while and then starts blowing "cool" air so then I crank up the temperature from, say 72, to 82 and it starts heating again... of course the blower speed stays low so I have to adjust that as well. The defroster kinda does the same thing but I bump up the fan speed to max as more and more snow falls.

Now, the weather warming, I have to use the A/C and now the opposite happens... at first it will cool OK with the temp set at 71 but then, after a while, I have to crank the temp setting to 60 to get any cool air and turn up the blower speed to get cool air moving.

I tried "auto" and that helps for a short while but not really great.

I took it in for service and was told "it's all normal"... Hard to believe this is normal! Our 12 year old Fusion does better.

Maybe I'm missing something?

My '10 did funky stuff like that. I didn't like it, but I accepted it. I suspect it is working as it is "supposed to".

it must be subjective to each owner being pleased with it, my ‘15 and 18 both work great... i may have touched the climate control 5 times max over the whole winter... mainly to use the max defrost feature if i had parked outside. my dad and sister both had fusions... one was a 11 and one a 13 i believe and i hated the climate control in both... i found it crazy that “auto climate control “ was a premium option yet you constantly had to mess with it to be comfortable... nothing really automatic about it. one thing i will say i noticed when i got my ‘18 is that i had to set the temp about 4 degrees warmer than i always kept it in my ‘15 but once it was set i normally don’t need to touch it. i set it to floor/defrost and around 74 degrees and i’m comfortable most of the winter with the fan on auto
