1. Find your vehicle's year and model. This is crucial.
2. Consult a repair manual specific to your vehicle's year and model. A Haynes or Chilton manual will be invaluable here. These manuals typically have diagrams showing the location of components like the blend air door motor.
3. Search online forums. Sites like CarGurus, Edmunds, or specific forums for your Cavalier model year might have threads discussing this exact issue, with members describing where they found the motor on their cars. Be sure to specify the year and model in your search.
The blend air door motor is usually located within the dashboard or under it, near the HVAC system. Accessing it often requires partial dashboard disassembly. Without knowing your specific vehicle's year and model, it's impossible to give a precise location.
