This blower motor has undergone some changes in design so the installation procedures have also changed. The original motor was a two piece motor and the wheel was secured with a set screw. GM changed the design to a one piece unit with a fiberglass heat shield and the wheel is pressed on. On some of the models you may need to remove the front cradle bolts so the engine can be rocked forward. This will help keep the valve cover from interfering with the blower motor replacement. On all models; disconnect the negative battery cable.
