is this for your a/c evaporator ? if so this is on the firewall passenger side should be a rubber gromet where the water drains out..

usually cleaning the interior air box and resolves any water discharge problems

i think so.. its to the point where i wash my suburban.. and water come up from the floor only on the front passengers side..

with a water hose deposit water into the air intake of the exterior heater/ac air duct...look for where the water drains out that is the point to inspect as well as removal of the air ducting in the blower motor area for debris..

you could also have a windsheld leak

if its the air ducting ,,,the interior. you should see it falling down from the bottom of the air duct..
