Climate controls

nzw212 · 11-01-2014, 08:29 PM

Why is the heat or AC, depending on what was on when the car was turned off last, come on automatically each time I start the car? I turn it off before parking just to have it on again when I start the car.

Thanks for any insight.

My guess is - these cars interiors are so well sealed, that if there is not fresh circulation from the HVAC the windows will fog and in certain conditions like rain the driver may not realize the windows are gradually fogging.

I asked my dealer this and his response: "to ensure the HVAC lines that run throughout the car stay circulated."

Thanks ATOMSAPPLE. That's a dumb design.

No idea. Annoying though, isn't it?
