For the blower motor, take out the cabin air filter and reach down in there and you will find leaves and trash in there. check there as all the bonnevilles that come to me have leaves and pine needles in there. Even mine did, and i have no leaves where i live lol.

Well finally went to tackle this project today, got a new blower motor, doesn't match up, there is no metal bracket with this one, its all plastic and doesn't have any drill holes. only the 2 plastic things that come down from the car is what is cut out. No holes for the screws, it says that a gm bracket might be needed. Has anyone else run into this problem? Anyone have a blower motors with the metal housing that is easy to swap like the one that is installed? I have the exact blower motor that is installed like in the Changing blower motor write up.
