I had two massive holes in the bootlid where the number plate threaded bushes were for about six weeks. Now there is loads of moisture on the inside of the windows and today there was ICE on the INSIDE of the windscreen! There are also mould spores on the rear seats and on the floor behind the front passenger seat. How do I get the dampness out of the car in this cold weather? I ran the air con on high for about 20 minutes and wiped all of the windows dry so hopefully it will retain that heat for a while. But I'm worried it's so damn in there, the windows will get condensation again in the morning. btw the seats are not wet, just a little cold to the touch. Any ideas? Heater or dehumidifier?
