Dash air blower problems
A while ago the dash air blower stopped moving air. The motor was running but no breeze. It comes off easily from under the dash. Turns out the plastic "squirrel" cage had disintegrated. I googled the name on it, a firm in Canada, who helped me find a new one reasonably priced and not too far away. It is an off-the-shelf item. Of course the new one was made in China.
After a while it got very noisy, especially in High Speed. I took the cage off the motor and sort of balanced it. This helped for a while. Then it got really noisy. This time it was apparent that the plastic blower had deformed and was hitting the housing. Using a heat gun, I was able to straighten it out some but it eventually got bent again. Turns out the spiral nature of the housing makes it very close to the blower where the spiral starts. Using a rotary file, I clearanced the housing. This left a hole in the housing which I sealed with tape.
Still running great.
