I have an 89 300se. I tore into the side over the weekend and have heard that if you bang the side where the blower motor is and the brushes are worn down, that it will sometimes jar it around where it will blow harder for a while. I did so and it did pick up some. If I could find the blower motor, I have the brushes and I would replace them. I was just wondering if you had ever had to do that?
