    my blower fan is only working when on Max. All the vent positions(heat,deforst,vent,AC) are working. the temp slider is working. But get no fan
    in low, medium or high. Any ideas?

    I assume this is an A/C car? You might want to shotgun a blower motor relay in there.

    and the winner is......blower motor resister. I could see where the wire was broken when I removed it. Swapped one from an old AC unit I had and presto it works on all speeds now.
    You guys know everything, Thanks!
