I've come across this thread today while searching for the cause/solution to my fan problem. Mine's slightly different from other on this thread in that my fan blows on all settings except position 2. Is this also most likely to be caused by a faulty resistor pack?

To confirm, I have a Focus TDCi, MK2 (2006) and the fan blows on all positions except for position 2 [edit], although it's hard to tell whether position 1 is working either; there is air coming out but does not seem any more than when on position 0. The air conditioning appears unaffected; it switches on at all fan speeds (although obviously doesn't blow any cold air out with fan set to position 2).

I'm at work right now so am not in a position to check for dodgy pollen filters, loose scuttle panels etc, but I've never been aware of any dampness in the passenger (or any other) footwell. I'll check the easy-to-access options this evening if I get a chance.

From the discussion above it doesn't sound like a blown fuse or a dodgy switch but I am loathe to fork out £20+ for a replacement resistor pack if it is unlikely to solve the problem.

What do you guys think? I'd be happy to supply more info if required.
