Heater problem

Hi guys.I do not have a question, but an answer. My previous question was about my heater not working properly.
I ended up taking the vehicle to the mechanic and it ended up that the problem was the blend door actuator. Whic was replaced with one from worldpac. Which is basically original after market. Seems it is operating ok now. Thanks very much. Oh and since I am kind of a tinkerer.I decided to open it and check it out, I found the motor is weak, which works when you give it a push then it stops by it self. Just being inquisitive. Anyway thanks again and best of wishes.
