Hello, I've had very a similar problem over the past couple of weeks on the same model (estate version). After doing a bit of research I am advised that the heater blower motor resistor maybe at fault. I obtained a spare of said item, opened Haynes at the right page and trundled off down the route of changing it to find that the heater assembly (and I guess, the resistor unit) looks quite different than the Haynes illustrations. If you do get this one solved I would be interested...also why the difference between my trusted Haynes and the real deal??
