The vent shades have peel and sick tape; just press them on doors. Clean the door frame with the alcohol pads provided, and dry. The ac on my wife's car went out, though she has a short trip to work, and not concerned about getting it fixed ($1,200 plus). On rainy days she roll down the window slightly to get fresh air to prevent the window from fogging up. These shads prevent rain getting in. Additionally I read having these shades stops the likely hood of a bug flying in while driving. Also they are suppose to help with gas mileage; roll down the windows a bit instead of using the ac. I don't know how much of this is true, or how much gas you save, if any compared to using the ac. The shades look good. Cost about $60 with shipping.
