How do you dry floor in car - 2006 Volvo S40

Get your heater core checked. May be leaking.

Use wet/dry vac to remove as much water as you can, then towels, then put car in garage open all windows and use some kind of heater to assist in drying. Make sure you have blown out all drains before going outside again.

You have a leaking heater , hose es or tap. That is why you are loosing coolant. FInd the leak by using a radiator pressure tester and replace /repair unit.

Is it water or is it antifreeze? If it is antifreeze you more than likely have a bad heater core that is leaking the antifreeze onto the floor of the car. If you just spilled some water and now need to get it out use a wet/dry vac and vac out the excess or soak it up with towels and let the carpet dry out. There is no "drain valve" or any thing like that to open up.

First thing we gotta find out where its coming from. After floor is dry sprinkle baby power on the floor and up my the fire wall and the check for the wet spots.

Possible causes: Lead in floor boards, a window replacement where the gasket was correctly installed.Drainage passage clogged for winshield
wiper motor area.

most common problem is the a/c condensor tube is clogged and is under the car and needs to be cleared with compressed air. also the sunroof track has 4 drain tubes and the right front may be clogged or leaking. you can check that by pouring a cup of water down the right front drain tube in the sunroof track and see if water comes out by the right front wheel

WHEN IT RAINS, WATER SEEPS THRU THE TRUNK AND NOW IS STANDING IN THE BOTTOM FLOOR OF THE WHOLE CAR.

It sounds like your heater core inside the car.

it all depends, it leaks out where ever ut can

1 - After wash your car verify if the doors are wet inside. If so you have to change the rubber.

2 - stretch news paper in the trunk and after wash verify if they are dry. If not, you have to change trunk door rubber.
