open glove box & squeze it together to open more to see blower motor. the fresh air door should be open in any position exept max air. there might be something in the blades.

thanks that worked great i did that and went under the hood and opened the blower from that end it wasent much trouble just the four screws and the fan pops right out found paper in there hitting the blade god only knows how it got in there but anyway i blew it out real good after removing the paper with a air hose and the noise has gone away and life is good again thanks for you help

thanks stephen
