I'm sure the air hose seemed like a good idea on paper, but in actual practice it doesn't as well as planned. How many other vehicles have you seen with an air hose to the blower motor anyway? My blower motor bearings used to squeal, but they haven't raised a peep since I rerouted that hose to the outside world (I PB'd the mess out of the bearings, then packed them with lithium).
