Okay, I just tested mine this morning and it was doing the exact same thing. It was blowing air to the windshield in Auto then change to feet and others as the car thinks is best and when the windows stopped fogging up.

So ur car is not broken, our GS is just so smart.

 

Yes you were 100% correct and I bet it has to do with rain sensing glass.

 

Fancy schmancy 2018 and 2019 owners!

 

Again, time to drive to the...


well u know the rest.

And if it makes u feel better, we still have to manually turn on the rear defroster.

 

FWIW, I dislike using Auto, I like being in control

 

My 15 did it too. Had the moisture sensor on the windshield.

 

Same here, would be hard to upgrade at all. I LOVE my 15...

 

I do like my 19 a bit more, but I really loved my 15 as well.

 

I bet. Test drove a 19, love the updated tech. Not enough to leave the 15, yet...
