1999 GA GT 3.4 temp select

I need some help. I have a problem with my selector switch. No matter what I select, whether it be defrost, vent, etc., the air comes out everywhere. Can anybody help me with this. Any help would be appreciated. Also if you know the part names and #'s, this also would be a big help. Thanks!

Did you check all the fuses & relays ?
Have you replaced the blower motor resistor ??

This does sound like your blend door is not working properly.
Its a pita to get to, under the center of the dash, and behind the radio area. It is operated by a cable/lever check that it is attached or operating.

Try here for the parts lists , and the blower resistor replace procedure.
