is there any "device" that can be plugged into cig lighter or hard wired that can come on and start to defrost the inside of the windscreen of the wifes car before i go out to do the outside? its a citroen C8 and in this kind of weather the ice is solid on the inside, cant seem to find a prob causing the ice to build up, no leaks etc but becvause the windscreen is so big and curved its a nightmare to scrape, and when the blower is on its like a snow scene when you scrape it
