Hello
If you gently slide your hand up under the HVAC system on the passenger side you should feel the drain hose sticking through the floor/firewall. Below is a pic where it is located approximately on your vehicle.
Next, if you look under the hood at the firewall passenger side, you will see your AC lines going into the evaporator. Look straight down from that towards the ground and you will see the drain hose coming from inside the car pointing down. A pic is below.
Next, I would first check the drain for being clogged.
