I have a 2002 Kia Spectra and the blend door actuator does not seem to move when I adjust temperature. It appears that it may have been that way for awhile (just bought the car) because the metal linkage between the actuator and the blend door piece seems to have been disconnected at sometime. It looks like the big white plastic piece on the blend door would have had to have been removed and then replaced to get the linkage disconnected.
What would be the best approach in diagnosing what may be the issue as to why the actuator does not move?
The electrical connection on the actuator seems to be a blue plug with maybe six contacts in it (I didn't remove that yet, since I wouldn't know what to look for with it).
I also do not have issues with hot/cold air if I move the blend door manually.
