I did start to remove the blower motor over the weekend, but when I realised that the squealing wasn't coming from the blower motor (the squealing was present with or without the blower motor fuse), I stopped and reassembled the car. Plus, it wasn't a slow reduction in the amount of air movement - one day the ACC worked, the next day nothing (except the squealing), and a very unhappy SO (she drives the car daily, not me).
I'm happy to replace the blower motor or the solenoids myself, I just don't want to start replacing random parts in the hopes that I get the right one - especially when I'm not convinced it's the blower motor (unless someone can persuade me that the motor will still squeal even with it's fuse removed).
