I am a new owner of a 08 Cayenne S. I am trying to figure out if my defroster is working the way it is supposed to. Basically when i push the button for defrost it goes to high fan and high heat. Then i have to manually lower temp and fan or it will run you out of the car. Other cars i have had would use AC on the window and keep the heat on everywhere else.

thanks.

 

That's how mine works.

 

that's how it works on all my cars, nothing to worry about..

 

Thanks for the reassurance. I guess i just have to get used to it.
