check how level a/c is in window. you want it level side to side and a slight pitch to the back. styrofoam is present for insulation in evaporator area could be squirrel cage rubbing on it.

Most window A/C units have styrofoam lining the air vent. Unless the manual says to remove a piece of foam when unpacking the unit, leave it there.

tilt your ac down on the outside,so it will drain properly,if that doesnt help,pour some bleach in the water inside to get rid of mold that clogs the drain

an Styrofoam.

Yes,some of them have it inside for insulation

Hello,Lilo The styrofoam pack MUST stay in place.When in operation the air tempature is so cold the unit will condensate(create water)if not insluated.Your unit would LEAK all over the place.The blower fan is a PLASTIC composit and should not rust.

After removing the cover and filter, you should be able to see the fins for cleaning. If there is styrofoam in front of the coil, it should not be there for proper operation.

Yes to the Styrofoam , If there is water running out the front of the system your drain is blocked and or the system  needs to be removed to inspect the drain tray and clean out if required.(serviced). As for it not turning on , check that the fuse isn't blown as the water may have shorted the controls wires and blown the fuse

Yes, they mostly juust use it for air flow

Yes it is supposed to be removed that piece is just for shipping. Good thing you asked. ken
