EATC code 21?
Does anyone know what this code means?
I had code 24 - replaced blend door actuator.
Got codes 21, 24.
Checked part number on box and looked it up, for manual climate control only.
Removed new actuator, and swapped new gears into old oem actuator.
Now I am still getting code 21 when I run the diagnostic. But code 24 is gone.
I have exhausted the search functions on this forum and Google. And cannot find a definition for what code 21 means.
