So, a question. Where does the spring go? I was fixing one of these and the spring fell out and I never saw where it came from.

inside 2 tubes that stick out opposite of each other just below the fan.

Spring goes on the one of the strips that slides back and forth….it has small end which goes in a small notched cavity of the plastic housing. Spring goes on that longer end of the stripe. See the picture in step 12…its popped out from the plastic housing.
