climate control

[peterk9]

There is no heat. As soon as the engine starts with remote start the fan is on high. It does not do this on a normal start with the climate control set to auto. Why?

As already stated, it is to warm up the interior as fast as possible. Of course there is no heat on initial start-up, that isn't the point. When you use Remote Start, the system takes it as no one being in the vehicle so the initial blast of cold air won't bother anyone. The temperature begins to climb as it runs and therefore it takes advantage of the slightest increases to help warm the interior. On normal start-up, it assumes that there are people in the vehicle and therefore will not automatically force them to sit in a blast of cold air. The system will wait until the coolant temperature has risen enough to make the air more comfortable. You have the option to over ride it if desired. That is the way the system is designed to work and it works very well.

Sorry, but Peter's explaination doesn't make sense to me. If there is a reason for it doing this what is it? No guessing or assumptions. I would like to know.

I can just as easily say you are the one making assumptions that there is no purpose. And it's not just Ford that does this - do a search, other manufacturers also run the fans on high during remote start. Here's just one example:

Why not do that during a normal start or once you start the vehicle when in it? Because even if the air temp is equal or only slightly warmer than the internal temp of the vehicle, it will feel uncomfortably cold to the occupants if it's moving at speed. Thus, once the car knows someone is now inside, the fans drop to normal speed. Would it make more sense for Ford to do it like in the Jeep example above and lower the speed as soon as the driver door is open? Probably.

So yesterday for the first time I had an issue with my A/C on my 2016 Ex XLT. I pushed the power button to turn it off and the a/c light flashed off/on but wouldn't shut off. Pushed it a bunch of times in different angles to see if it was the button but nothing, still wouldn't turn off. Went into the a/c controls through the LCD and hit the power and it turned off. Hit the main button it turned on then pushed it again to verify it turns off and it did.

I was driving on the freeway tonight and it happened again. Wouldn't turn off. This time I tried pushing the power button and I the seat heater button next to it and it turned off.

So basically I found that when it fails the only way to bypass is by going through the LCD or holding the power button down while pressing another button.

Ford still has fixed the odor from the vent and now this. Bummer.

Seems to depend on the manufacturer. My 13 year old Saab does not have the fan blast until the engine if properly warmed to provide actual heat whether with remote start or not. And, my Saab still starts blasting warm air twice as fast as me Ex.

I for one wouldn't want the fan speed lowered just because I opened a door to get the ice scraper out.

Lucky for us, I assume the same for both 2015/2016 models, that the fan stays on full blast from an autostart, until we are ready to "start" the vehicle and drive off.
