How to dry out my car?

Hire a small dehumidifier,run an extension lead through the window,then close the window as much as you can,let the de -hum run for as long as you can, a weekend should do it.

Is there a smell in the car when you run the fan or is the pass. side floorboard wet? It sounds like a leak in the heater core or one of the connections to it. If not longer periods of running the heater on high heat & high fan should eventually dry it out.

check the floor board to see if it,s wet from water or snow on your feet.

5 litres of BPs finest un-leaded should do the trick. Just sprinkle evenly all over the inside, stand back and toss a lit match in the open window

make it into a convertable by chopping off the roof

sell it

If the car did not get real wet on the inside, you may have a leaking heater core or clogged A/C drain.

If your car heater has an option for choosing fresh air, or recycle the air - always have it on fresh.

Keep all windows open a few inches when you're driving too.

Also, try not to park in shaded areas.

Place one of those dehumidifier cell thingies in the car this will absorb damp air.

These were once available from Woollies but now I reckon Wilkos is your best bet. good luck.

at some point your car has got wet on the inside due to a leeky seal or just leaving a window open, but anyway when it defrosts the moisture stays in the car, you need a dehumidifier which will remove all of the moisture, i had to do this with an old car where the sunroof leeked, and it removed over a pint of water overnight.

Fix the problem! Water is getting into the car from SOMEWHERE, possibly a failing windscreen seal or the sun-roof drain-channels are blocked, or a hole in the floorpan under the carpet, or the bulkhead behind the dash... it may be hard to find, but find it you must! Only with it fixed, can you hope to dry the car out.
