The blower switch campaign 01M07 addresses only the blower switch and its connectors. The symptoms of the switch going faulty are one or more (or all) blower speeds going offline. The blower switch's operation is independent of the mode selected, that is, it is to be operational in all modes except OFF.
Since the acutal fault is still not clearly described, we probably need to wait for a better and more complete description.
