I know this is an old post but the idea is the same. I remember back in the sixties when I was a kid there was a guy that bought a brand new Chevy Impala from a local dealership and had so many problems with it and still couldn't get any satisfaction from the dealer or GM , that he went to a local store and bought a whole case of yellow plastic lemmons and screwed them all over the car with a sign that said he bought this lemmon at ( NAME OF DEALER ) and drove that car around the area for many years. Unfortunately that same dealer is still in business and is still screwing the customer.

You should change the blower as far as my concern.
