ford mondeo 06 car is always full of condensation
If you car gets cold and the humidity is high you will get condensation. Just a guess but you are probably parking the car out in the open? Parking it in a garage or car port will help a lot. Get a moisture absorbent and keep it in the car which will dry things out. Also check for window/door leaks that may be getting your carpet wet. http://www.amazon.com/DampRid-FG50T-Hi- Capacity-Moisture-Absorber/dp/B0029EGUNG/ref=sr_1_1? ie=UTF8&qid=1447089306&sr=8- 1&keywords=moisture+absorbant
On warm days open the windows and ventilate the car out and then close it up at night. Check for leaks though.
