Hiya, 2002 Punto. Turned the heater on Fri and it made the usual noise for about a second and went dead. Now no heater or demister. Most people I have asked suggest a fuse has gone ! (is this right? ) Looked in the handbook and can't find any mention of a fuse for the heater/demister. Is it likely to be a fuse or is it something more serious. If it is a fuse does anyone which one. Many thanks.
