the front passenger side floor is wet, with ac on. The liquid appears to be clear.Any idea? Is this sweat from the cooling coil?

You are correct, unless it has rained or you washed the car, it is most likely this is from the evaporator (sweating cooling coil). There is a drain hose that connects to the evaporator housing that may have been disconnected, or it may be plugged. Best of luck!
