When I run the AC there is water behind the front passenger seat, even happens when I run only the front air. Could the condensation line be clogged? And if so how do I unclog it

It sounds like condensation. Check under the hood on the passanger side firewall. There should be a black rubber hose pointing down to nothing. Make sure it isn't clogged. If it is, chances are it will be right at the end where dirt can get into it.

Let me know what you find.
