Regarding the HVAC: I can switch between upper, middle, foot no problems and air blows from all locations accordingly. A/C blows cold, air is not restricted, heater is hot, auto setting works too, defogger works too.
Strange thing is with or without the HVAC on it makes that noise during start-up.
It's like there is a mechanism in the dash that moves each time the car starts and if the car has 15 minutes or more to sit the mechanism resets or settles down (from gravity or such) allowing it to make the noise again when the car starts-up again.
