What's an effective way to dry up a car's wet carpet and seat?

Last night I accidentally forgot to close on window on my car, and it rained a lot. So my carpet's are really wet and so is my seat. Do you guys know of an effective way to dry it up? The carpet isn't stuck to the ground of the car, so I'm afraid there may be water underneath the carpet, and that it will become really moldy? Does this mean I should eventually replace the carpet?
