Hi im onto my 2nd mondeo mk3, and wondering how quick the quick clear screens should be? my first mondeo lx was very quick at defrosting ice, it wouldnt take long at all to defrost the screens, but my zetec s seems to take ages!! my heated screen lights come on automatically so i know its working, i even have the wipers set to come on intermitent to aid to clear the ice but its so slow and can take upto 10 minutes to clear, is there anything that can or will be slowing the defrosting? thanks and hi to all the forum.
