HVAC Fan speed blows at higher volume.

[Brent Karrett]

Does anyone have an answer for this? While set at fan speed “1”, The HVAC periodically blows at a much higher volume. Highway speed, usually on an incline.
WTF?

A/C cutout? Not sure if Maverick will shut off the compresssor under heavy load but the vehicles I've ridden in that do, typically run up the fan speed to cover up the shutoff.

Check your cabin filter.

If it is a hybrid, its electric AC compressor does not do that.

Try setting the preferred speed to 2 instead of 1. If fan set speed on automatic cannot hold cabin temp within 2 (or 3 possibly, not sure) degrees the ac will adjust fan speed and probably ramp up condenser also to bring cabin to set temp.

Hi there! Will you send us a message with your VIN and your local Ford dealer? I can look into things on my end.

My 2022 XLT Hybrid does this daily on my commute. It's a long (85 mile) commute each way and I've noticed it doing it a couple times during the drive every day but never thought too much about it. It doesn't seem to do anything other than blow out harder for a minute then it reverts back to the lower speed

From what I understand that’s normal function. It’s to keep the cooling tubes from freezing over. Once thawed it should go back to normal

Turn off the "Auto" Function.

The Auto will increase the fan speed to keep what you have the TEMP set to.

I hate the "AUTO" Function as well. I am fine if the temp goes up a couple of degrees. The fan on HIGH is LOUD AS HELL!

Fan output increases anytime lower than 68 is set on either dials.

Fan output increases anytime lower than 68 is set on either dials.

Only if you have AUTO on or MAX A/C. I drive around all day everyday with the Reg A/C with or without Recirc and both dials set to LOW and my fan is set to 2 notches and it stays at 2. But If I hit Auto and the dials are set to LOW Yes the fan go Full on Hurricane mode. The fan goes to full blast as well when I hit MAX A/C
