Com theres steam coming out of the vents

Is it steam from your car overheating? Or could it be a freon leak? When you say steam is coming out of your vents, it doesn't give us much of a place to start.

''sweet smelling'' steam and overheating light is on.

your heater core or heater core hoses are bad and have sprung a leak the sweet smell is from antifreeze this is not a do it yourself-er if you are squeamish about tackling a big job sometimes they can be a real pain to get, like the built the entire car around it.
