Does it turn clockwise or counterclockwise?
Answer Hello Tkoster. Counterclockwise to release and clockwise to lock into place.
I could not find a screw to turn. Does it pop out or does it screw out?
Answer Hello Charles. There is no screw. You insert the flat tip of the screwdriver into the vent 8545536 and turn the vent. These can be VERY tight and hard to remove. Hope this helps.
How do you take off the vent deflector?
Answer Hello Chick6148. You will insert a screwdriver into the slot on the vent deflector 8545536 and unscrew the locking tabs. About 1/3rd a round and you can remove the part. Hope this helps.
