Lexus HVAC air door actuator replacement RX300 2003

The issue l was having, is the air was only coming from the floor vents. I bought a blend door off Amazon. Probably not as long lasting as a OEM part which lasted 21 years. l have over 250k miles on my Lexus. https://www.amazon.com/Actuator-2002-2010-... l should have replaced the cabin air filter, but did not have a fresh one. https://www.amazon.com/Denso-453-1012-Filt...
