    Default ::.. Blower slow and vibrating on high

    And on to the next problem. Blower is starting to be really weak. Barely goes at 1 and 2 so I usually crank it to 3. At 4, I sometimes feel a vibration near my feet, so I don't turn it there.

    A little searching turns up this useful thread:

    So my general question... is this the only way to get to the blower and see what's up?:

    those pictures show pretty much how it's set up, i wouldn't bother with the old motor as they are usually toast, with the comm eaten up like they are usually are it won't last long with just a sanding and new brushes, that will probably get it working but theres the possibility it will burn up something by drawing too much power

    Mine is the same, no air blowing much till 3 or 4 and then not much. Could it be a dirty cabin air filter causing it or is the motor gone?

    Thanks winfred. Looks like I'll need to scrap away a few hours to take it apart to look. About $150-200 for a new blower eh? :|

    Dirty filters put strain on the motor cause it cant pull any air.

    Default On his early car its not the filter but on your newer car its most likely a plugged

    up filter, the motor probably isn't hurt

    If there is no air filter the fan itself might be dirty enough to cause it.

    I am taking mine in today to have it (microfilter) changed, noticeable lack of airflow and bad smell when I turn on A/C. Also having 4 new Bilsteins installed, window regulator, and Mobil1 oil change. Can't wait to get it back as I have to drive a '98 Buick Regal until I do. :-(
