A couple of questions for you first, does the moisture smell kind of sweet and if you get it on your shoes or fingers is it slippery? if so then yes it is coolant. if not then start looking at windshield seal, door seal, check to see if floor board only gets wet when it rains or water runs over the car. be careful because your air conditioner can cause the same issue, there is a drain tube that runs to the bottom of the car, you've seen them drip in the summer time on the pavement, if it gets dirt or debris in it it will back up into the floor board also. not sure what type of climate you live in so there is a couple of ideas. check your coolant level and make sure that it is not low also, if so have shop pressure check it and see if it bleeds down pressure if so then you do have a coolant leak. does the heater work fine or is it intermittant? if intermittant then definitely check coolant level, if coolant is in the floor though it is for sure the heater core. hopefully this helps, just a few ideas to check to make sure before doing this small costly repair. let me know if i can help in anyway. thank you

If it is antifreeze, yes. It could be just water from a clogged a/c drain or rainwater leaking in from a bad seal.

Why do I have cold ac on driver side and stale air on passenger side. what could itbe? and notice water and antifreeze on passenger side floor board well at least that what it smells like like to me.

antifreeze anywhere inside the cabin is a sign of a leaking heater core. Rub the liquid between two fingers. If it feels oily, it's coolant.

Form of liquid, looks like water leaking into passenger side floor board.

I would have to say it is probably your heater core or one of the hoses that run to it. The heater core is basically a small radiator but is located inside the car so when you want to heat the inside of the vehicle, the water that normally circulates through the engine is redirected through the heater core and with the aid of a blower throws the hot air out.

Getting water in front passenger floor boaed, what might cause it?

Clogged or disconnected drain hose from the heater core box. Or bad/leaking heater core. Does the liquid smell like coolant. If so bad heater core. If not and the water only when you use the AC then it is a drain hose issue. If neither of those pan out you could have a leaky windshield. However 99% of the time a wet passenger floor is caused by a bad heater core or drain hose.

Water on floor board on passenger side of 1991 Buick Century

Engine coolant will feel oily and the windshield will fog up and the car will stink. If it is just water it could be coming from the passenger door weatherstrip at top. The ac drain tube , if stopped up will also leak water in the floorboard.

Does my 1997 toyota land cruiser have a heater core?

Check with Toyota Parts. I'm sure there is one, but it is unavailable at a retail parts store. Heater cores are pretty much as necessary as the four tires on the outside are. My advice would be to remove the core and check the hose clamps or connections for other issues. You want to be sure that the leak is in the core and not in one of the hose connections. I think that is odd that your driver side floor is wet and not the passenger side. Open the hood and look for coolant hoses attached to the firewall (the sheet metal between your dash and the motor) and see if they are on the driver side or the passenger side.
