Thanx Howdo, after a lot of trial and error, and advice, discovered it's the 'resistor'... Temporary fix so blower works full blast as if number 4 but turn to number 1! ;) Fused so should be safe until can do proper repair...! :o Need a battery now, been showing battery warning light on dash after starting engine for a few weeks so better be safe than sorry! :) Still love the car! Happy and safe driving all in this weather... x
