Welcome Photochief.
Problem number 4 can probably be forced to happen by switching the ventilation system in and out of recirculation mode. If so, the problem can be solved by lubricating a certain vent door. If you are under warranty, demonstrate the sound effects for the dealer and ask for a fix. I predict better results if you demonstrate by switching recirc on/off than if you just make the sound yourself.
If you are not under warranty, I doubt there is a DIY fix.
Problem number 3 can be solved but it depends on which radio you have. I don't know the instructions for your radio.
