I have a 2012 200 2.4l. I got the typical blend door actuator failure "clicking noise" and replaced the actuator with a Dorman actuator a year ago. A few weeks ago the car developed a creaking noise every time the blend door actuator would open or close the door. It sounds like the car is haunted or has gastrointestinal problems! The new actuator seems to be working, i.e. the actuator isn't clicking from a broken gear and opens and closes the blend door. I bought another new actuator and was going to put it in but was wondering if anyone knew how to lubricate the actual blend door itself, or if they had experienced and figured out what the blend door creaking was caused by? I thought maybe I could lubricate the blend door hinges while I had it apart, but they aren't readily accessible as far as I can see.
