The plastic trim around the bottom of the doors, pull the front back away from the A pillar, then gently lift the sill part up and the carpet is ready to come out. The foot rest is not easy!

As to the insulated rubber liner, it is in 2 pieces - front and rear. It does not come out!! I suppose you could cut it out in the floor pan sections, but getting it back will be a real problem. Do not separate the foam from the rubber as you will never get it back properly and the floor will be lumpy.

Because it is water and not antifreeze, it will evaporate - slowly. If it is as soaked as it sounds, try pushing the water from the center side to the back rear and use a shop vack to sop up the water. Save a sunday paper without the glossy stuff and stuff the entire newspaper (flat) under the foam as far as you can. Let it sit and repeat when wet.

Park in the sun with the windows slightly lowered and let the heat be your friend.
