Some people have found it behind the heater controls switch panel, others under the drivers side of the dashboard. I kind of hoped there would be some uniformity in the location but it doesn't appear so. A replacement resistor pack is about £14 on eBay and hopefully this will fix the problem. This method of controlling the fan speed is very common amongst all vehicle manufacturers as it's cheap and cheerful. Problem is the resistor gets hot and fails very frequently so nice little earner from the garage who were going to charge £89 to fix it!!
One of the benefits of MHF I was told once to always run the fan at max speed for a second or two before turning off, never do mind, and only had to replace two ever.
