Hvac fan randomly changes speed

[scyntaxx]

I have 2 hvac fan issues.

1) Has anyone else encountered a problem where the hvac fan will increase speed on its own? I have noticed that on long trips, it'll randomly get louder and blow harder without me having to adjust it. When this happens, there is not a notification on the screen.

2) I also noticed that sometimes I'll get a fan speed notification on the infotainment screen. Usually when this happens, the fan isn't actually increasing speed. It's like the truck is just letting you know the speed for no reason.

Is the auto mode illuminated when that happens?

No.

No.

Sounds like an issue then. The dealer will need to look at it. That shouldn’t happen. Could either be a fault or a glitch in the console software. Not sure if the radio software controls HVAC also.

I don't know if this is your situation or not, but...

When I give a voice command or make a phone call the fan slows down to reduce the background noise. Then it speeds back up again.

Anything that uses the Mic ( bluetooth, Android Auto, Carplay) will turn down the fans while you are talking, could that be it ?

I actually think it is a neat feature.

First problem I have had as well. Only on longer interstate trips. Second issue don’t recall seeing.
