Climate control blower fan seems slower after update

[BeardBros]

So my truck did an update yesterday by itself while it was parked outside my work. I saw a notice on the DIC that said an update was ready to be installed and I could not do anything with the truck after it started. I said why not, probably some good software fixes, so I hit OK and went in to work. Now it seems like the climate control blower motor is missing its high setting and doesn't run as fast as it used to. Anyone else notice this? There also seems to be some glitchyness with the intellibeam  after the update also. Of course is has been -30 degrees here for 2 days. That always seems to wreak havoc on new cars electrical systems, but I think the update messed with my climate control system.

What version of software do you have?   Was the update V509?   I had that update yesterday but haven’t been in the truck to check things out yet.

I knew it wasn't in my head.  I'm experiencing the same thing.  Still heats like normal but I definitely noticed the blower doesn't seem to kick into high when I switch between Footwell/Defroster and Max defrost.

Experienced it yesterday.. Update was done, heat is fine but fan is very low output. Switched to max defrost and no change in fan speed..

Same here.

Is the update maybe just inadvertently lowering the “auto fan speed” in the infotainment’s vehicle settings? I can’t say I noticed any difference really.
