Since I've had my S40 (2002 phase 2) there's been an issue with the demister/blowers whereby on certain settings (that have no pattern, sometimes when on 3, sometimes when on 5 and so on) whereby it will blow as normal, then suddenly really fast, then barely at all, fast again, and so on. Moving the dial to another number usually stops the problem but it reoccurs on different settings on occasion.

Is it worth pursuing or should I just put up with it?

Thanks in advance
