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.

Coolant leaking on passenger floor

Sounds like the heater core is leaking. The heater core is located inside the vehicle, usually contained within a plastic box, when the heater core leaks enough, the plastic box will fill up with coolant and eventually leak out, usually onto the passenger side floor. Hope this helps.

Leaking Coolant inside passenger side, coolant fumes inside.

Hi, its definitely the heater core that is leaking at this point. replacing this core will fix this issue. In the mean time, you can shut of the flow of coolant by using the shut off valve near the core. this will prevent anymore water damage until you can get this issue repaired.

Please rate and have a great day:)

Antifreeze/coolant leaking from under passenger side dash

If it's your heater core, unless you're a mechanic you probably should get professional help. The heater core is located on the firewall and many parts need to be replaced to get to it. Do you see water on the floor inside the vehicle, Many times a heater core will leak inside.
