I have a 2003 Chevy Impala and the blower motor is rubbing on something and it vibrates the whole dashboard bad can i fix this and how?
You can fix it by replacing it with a new one, but make sure the one that is already in there has all the retaining screws (no empty holes). I have added the replacement procedures below. Heater System Blower Motor Removal & Installation
To Install: 1) Install the blower motor. 2) Install the blower motor mounting screws. 3) Connect the electrical connector to the blower motor. 4) Install the under dash insulator.
