I'm wondering if any of you have experienced the problem I'm having with my 159. A couple of months ago the heater blower just started blowing at full pelt and wouldn't stop when i turned it down. To make matters worse it wouldn't stop even when I turned the engine off and removed the Key, the only way it stopped was when the battery ran out. The problem seemed to have gone once the battery was charged but then last week it happened again and won't stop unless i run the car with the fuse removed.
Any advice is much appreciated
