I did a search in manual in car. Didnt find anything. Except some generic messaging.

anyone know what the 3 lights designate?

Total guess - but perhaps fan speed?

The dot on the auto button each represent the fan speed output to get to the temperature that was selected on the rotary dial only when in auto. 1 dot is slowest fan speed, 2 dots medium fan speed, 3 dots is the fastest fan speed.

I think of it as, "How aggressively do you want me to pursue the temperature you selected?"

"I'll get there eventually."
"Right away,sir."
and
"DO IT RIGHT MEOW!"

So adjusting fan speed in auto doesn't kick it out of auto?
This is an improvement over previous Ford's.

This is kinda what i figured. But also thought it kinda strange for “auto”. But makes some sense. to be honest i cant really tell a difference. But ive mostly been riding with the front panels off in slightly colder weather. And auto doesnt do jack.

Think of it as
Auto low= 1
Auto medium= 2
Auto high= 3

So it changes the maximum fan speed attainable based on the level you pick.

Adjusting fan speed manually will turn off the Auto mode.

As others have said the three modes represent how aggressive the HVAC profile will be. 1 is more of a courtesy mode to keep things quiet, 2 will sit in the middle of quiet and circulation and 3 is for moving as much air as possible.

I’ve usually kept my Fords and Lincoln’s on 1 and have always been comfortable.

So the Bronco just has a 3 speed fan adjustment?
Of course in auto, it's infinitely variable...
Same with auto/rain sensing wipers. Way more than just high/low

 

[WuNgUn]

Apologies no not at all. The fan itself is manually adjustable with 7 speeds

The auto mode has 3 settings that control how agressive the fan behaves

Sheesh... Okay. So are there 7 LED's somewhere to say what manual speed the fan is in? Lol

 

[WuNgUn]

No it’s displayed on the Sync screen when you make a change

Ahhh... Okay. Thanks...
My Escape is devoid of any climate controls/display in the Sync screen, but some markets have it

Thanks posting this question. Just got my Bronco. Now that I know what it Js I wonder who cares? Of course the fan will run hard and then slow as it approaches desired temp. And if it didn't so what.

People on phone calls in their Bronco care. If you have to hop in the car and take an important business call, having the fans blast on max can be disruptive. Having an auto option that keeps the fans muted can be helpful in this case (which is frequent for me).

I had the same question. I found the answer in the owners manual that is built into Sync 4. It actually can help. I know this doesn’t help those who don’t have their Broncos.

If your phone is connected to the truck, it will automatically slow the fan speed so you can talk and hear. At least other Ford's do.
It should also do this when hitting the voice command button but it's not the case for me...

Indeed! That's a very cool feature IMO. I found the official Ford HVAC page here. On these two topics:

IF YOU HAVE AN ‘AUTO 1-2-3 SYSTEM’…
You have the ability to adjust how much air flows through the vents. Use “3” if you want more air flowing around inside the cabin, “1” if you want a quieter ride, or “2” if you want something in between.

IF YOU RECEIVE OR PLACE A CALL WITH YOUR BLOWERS ON…
The blowers in your climate system will automatically lower so you can hear and be heard better. Once the call is over, your blowers will return to their normal level. If you want to exit the voice blower limiting and bring the speeds back up, press the blower up button. Voice blower limiting will also disengage if you press MAX DEFROST or MAX A/C.

That's very cool. I still hate fan noise, so I'm the type of customer who would keep it at 1 light.
