Temperature control fan randomly stops?

[emwolter]

I have 2023 big bend and the blower will randomly turn off in both the ac and heat mode. It comes back on after a few seconds. I can’t reproduce it for the dealer so it gets challenging to have it evaluated. Anyone else having this issue?

Did this happen after coming to a stop and the auto start kicked back on again?
They'll do this for some reason after the engine restarts.

No it happens while I’m driving

If you have the Auto (with 3 lights, 2 lights, or 1 light) pressed or “on” then the ac unit will kind of do its own thing.

I usually manually adjust my temp and fan speed (auto lights are “off”) for my preferences and it tends to do what I want/expect.

Maybe try turning the auto lights so they are off and see if the issue continues or not.

Possible it’s the “auto refresh” feature of your HVAC. To keep your Bronco from killing you with carbon monoxide.

Every 30 minutes or so it will switch out of recirc and pull in fresh air for just a moment. This causes all sorts of shenanigans with the Automatic climate control for some reason

Not sure if that’s your issue but it’s made a lot of folks scratch their heads when it does odd things out of the blue - a lot like you describe

The fan also slows down when you have an incoming phone call over Bluetooth. Related?
