My car is obsessed with A/C

[E90alex]

I still don’t want it and it’s still not needed. For god’s sake, it was colder outside than the thermostat setting. And I had left the windows open, so the cabin air was equilibrated with the outdoor air.

The car should not be aggressively pushing cold air on me or the cabin when I don’t want it. Can the owner get some respect from Ford?

Why would it be blowing cold air if your temp setting is higher than outside? If the air is too cold then make the temperature warmer. Just because AC is on doesn’t mean the air coming out should be cold. And just because the AC button is lit up doesn’t mean the actual AC is even running. It’s not all or nothing.

You are capturing my annoyance. It makes no sense, as I’ve been trying to convey. Yes, blowing cold air when thermostat setting is hotter than the cabin.

“Make the temperature warmer” -ah, no. I’ll just turn off the A/C, over and over again

Doesn’t the AC system also cool the Hv battery system?

May have something to do with that.

It would be an extremely badly designed system if this was true. Your needs for cooling/heating are different from the HVB. It uses the same heating and cooling system, but it uses valves or such to direct what is needed to the HVB and the cabin.

This is probably going to annoy some folks but to me the current auto system is, if anything, not aggressive enough. We’re starting to get to cool weather in upcountry now. I find the auto system is very slow to react to fogging windows during my morning drives. It anything, I wish it did its thing sooner and more often so I don’t have to on our winding roads to town. YMMV.

Right? They have dealerships for disrespecting you

1. Bought car.
2. Set auto to 72.
3. Haven’t thought about it since.

Ditto. Works like a charm. Warm when you need it, cool otherwise. 72 is my preferred temp too.

Why is that badly designed? We both need temperature control and it’s was more efficient to use one system to do both rather than two.

The real question is: Are you as the driver able to get the interior temperature to be the temperature you want?

So far in my almost 4 years with this car, the answer is yes.

The OP’s annoyance seems to be tied not to the above but the perception that there is energy wasted based on the system design and AC compressor running when it doesn’t have to.

I was just suggesting the idea that maybe the AC running “isn’t about you” and it’s about the battery temp which would be to help efficiency and reliability.

This is usually the point in the discussion where @MachLee shows up and explains how it works.

It loves to start up with A/C on. I could understand it if either of these were true:
1. I used it on the last drive.
2. It is hot out.
But A/C comes routinely at start up when neither of them are. Right now it’s 67 deg F and it gave me A/C.

I checked the vehicle menus for a setting - no luck. I checked these forums for this issue - also no luck.

Anyone have better luck than mine?

I have a 2021 MME select and I have notice that the A/C works better now than when It was new. Was it an update?? A minute after entering a hot car, the air is comes on and it is actually cool air.

AC being on has nothing to do with air temperature. That based on the temperature you set.
It drys the air.

The auto climate system is trying to keep the inside dew point well below the temperature of any surface the inside air encounters, avoiding condensation, particularly in places like ducts where mold could grow. This is usually a good thing. (If you live in the desert, far, far from Louisiana, maybe you don’t need to worry.)

AC cools the air. In a heat pump system it can cool or run in reverse and heat the air, but either way temperature is changing.

Drawing out humidity is a byproduct of this process.

Do you use the FPP-89 filter? It could be happenstance but after I installed it I believe it restricts airflow enough that I've noticed my car does not defog as well as when I was using the original filter, like the algorithm just doesn't work quite as well now.

Climate control is a time based affair vs the distance drove and is significantly less, ever with head, than the car uses to move itself as was pointed out.

except when my wife messes with it.

Too cold, even in Texas, lol.
