Hello

Are both of the given sentences OK? Is there any change in meaning?

1- Roll down the car window, please.
2- Open the car window, please.

Is
roll up= close?

Hi Tom

Nowadays cars often have a nice set of buttons that open and close the windows electronically ("power windows"), so very technically speaking, that's not really "rolling" the window down/up. That's pressing a button.

Other than that, yes, your sentences mean the same thing.

And yes, in car without power windows, you could definitely roll up the window.

PS
I drive a cheap car, so I always have to roll the windows up and down manually.
