You went through back to the previous area and then send back when you felt in a ravine, now the problem is that the door is operated with a button on the other side.
You can't fix this problem because you have to be on the other side of that door to push the button.
The only thing you can do is to finish this level and then restart this level, the most puzzles should be resolved. You have to open some doors because of the wind, when you are at the right place pick up the third rune and then exit this level. That should do it.
This is the only way to solve this because the button is on the other side of the door.
