A. Yes. As per the answer to Q626 , the intent of "Select Automotive Motors" is to limit the selection criteria of automotive motors to those specifically listed in the parenthesis that immediately follows. "Door" motors are listed, and a motor sold as a "Door Lock Actuator" does fall under that category.
