Water build up on passenger side carpet

I have a 95 sc300 5 speed and when I run my A/C for about 20 to 30 minutes it will form a puddle of water in the passenger footwell. The water is coming from up under the dashboard. I ran the A/C diagnostic and it gave me codes 21 (Solar Sensor Circuit) and 43 (Air Outlet Door Position Sensor Circuit). Could it be possible for these to cause so much water. It is water its clear and no smell and taste like nothing.

Do you notice water droplets underneath the car as well? If not, then the drain from the evaporator core may be clogged causing water the drain into the car.

No I haven't seen any water from under the car so its a possibility, but what about the code 43 would this have anything to do with it.

This is ur problem. Find the hvac box drain tube on the firewall or towards the bottom of the vehicle in that area of the passenger side of the car. And try to unclog it.

No the code would be completely unrelated.

Use a metal coat hanger. Don't go crazy with it though, light pressure should be more than enough.

I'm having this problem, but I can't find the hose. I can't get too far under to see beyond the large empty spot, but I don't see the hose there. Is it closer to the center of the car? Anyone have a picture of where this hose is?
