I think you have multiple issues. Fog or steam coming out of the vents and you having a film on the inside of the windshield is an indication the heater core is leaking. So you will be low on coolant, and potentially have an overheat issue due to the low level of coolant. Replace the cooler and the rubber hoses. The serpentine belt falling off is due to a worn belt tensioner or pulley issue. Replace the worn pulleys and or tensioner with the belt.
