I have a leek in my car, its the passenger side at the bottom

Check the rubber molding around the door. Look for any type of uneven or worn area. Are you getting any wind noise thru the door while driving? Also make certain that the door closes tightly.

check heater cor inlets.

More then likely coming from your heater core, You can try to stick a wire clothes hanger up the line on the passenger side under hood on firewall, Is a hose this may be stoping up not allowing coolent to run through system. If this don't work you need to take and have pressure tested to make sure it's not nothing worse, Turn your heater on and see if this cools it down and If so you need to replace the heater core. Best of luck to you, Sorry can't be more direct but this could be many issues,

the leek, ac tray inside the passenger side has a tube that carrys the water out of the car and it might be clogged up
the lights , fuse maybe

The best way to check this is with a radiator pressure tester this will allow you to pressurize the system and find out where the leak is.

the AC water condensation drain is plugged, as soon as u clear this the leaking will stop, the drain is under the car on the passenger side at the bottom of the engine firewall, u will need to raise the car up to see it and clear it.

sounds like a leaking heater core or heater core hose

no it's the water heater core costs aboyt $75.00 and costs $100.00 labor to replace, will need new antifreeze and thermostat and gasket as well.

Either the heater core is leaking or one of two hoses to it is leaking.
