The drain is located on the passenger side of the vehicle. It comes directly from the HVAC box, through the firewall, and out of the vehicle.
I attached a couple of pics below. Let me know if they helped you locate it.
Also, if you find it isn't clogged, let me know. I have to dig through some things, but for some reason, I remember a technical service bulletin that may help.
Let me know if this helps.
See pics below.
