How to figure out which blend door actuator is bad

Jun 10, 2019 · 74. Reaction score. 14. Location. Nashville, TN. So replaced my passenger side (upper) blend door actuator since I had the famous clicking/knocking, and mine actually was constant and never stopped. After I replaced it I still get a few clicks once I start the truck and then it stops. AC and heat work how it should and have both.
