Passenger floor getting wet

the a/c is making a lot of condensation and its leaking into the passenger floor board...what do i need to check to make it stop????

The drain tube comes out inside the engine compartment on the firewall behind the engine. It's right near where the passenger's feet would be. There may be a U-shaped cutout in the foil insulation hiding it. Stick a small hook or screwdiver in to remove the clog. It may help to run the A/C for a bit to build up water behind the clog so that when you loosen it the water will flush it all the way out.
