1. Sounds exactly like the tsb for the hvac fan. I don't think the foam strips were part of the tsb. I think they were actually an intermediary fix on vehicles within a certain production run. If I recall correctly, the tsb fix included a different vent system under the front cowl. There's a thread out there on it. Might want to ask the dealer about it.
2. I have had weird locking and unlocking since day 1. I think it may have to do with the sequence of starting my car (ie. start the car get out or start the car and get out to open the trunk) If you can only replicate it below a certain temperature, then I think you have something different.
