Again cheers for the tips. Got home today and thought id take a look at it. the snow as now melted so i put new fuse in and gave it a try. As soon as i put the blower on there was a big bang come from the back of the controls and the blower started working. ive just tested it for half hour and alls good. Dont know what happened but i not complaining.
So now i got heat and moving air. now for some arch repairs and im good. Again THANKS
