Where is the A/C condensate drain line? (and can I get to it and unplug it?) One day of driving with the air on and the passenger floor is soaking wet (no rain in weeks) so I guess the drain is stopped up. I have been under the van but can't find it.

What is your question?

I understand that the drain can get stopped up and condensate can back up and overflow on to the floorboard. This happened before on a long trip with the air on then again recently. Previous owner parked under trees and I flushed out debris from under the intake air screen and that all flowed out properly through the wheel wells and none got inside the vehicle (no leaks from the outside). I can not find where the condensate box drains to the underside of the van.
