The back seat on the drivers side of my 98 camry is always wet, soaked in fact. There are 2 small plastic ducts located under the drivers seat , facing the back seat. I assume these are part of the heating/air conditioning system. I was wondering if these ducts could be the source of the water. The air conditioning still seems to work fine.
Has anyone else ever had this problem? If so, please let me know what the solution was.

A lot of times people mistake a leaking sun roof for water comming out of the pipes.
If you have a sun roof you need to blow compressed air in the two drain holes to make sure they're not plugged. (Start at 40psi and go up from there).


Check the expansion valve on the A/C system.

I had that also, same year, same model, but it was under the passenger seat.

It seemed to resolve by itself but I'm still trying to figure out what could've done that.

This comes up often. There is a drain tube under the engine that carries away moisture from the AC, the water you see dripping underneath a car standing still on a hot day with the AC running. When the tube gets clogged, the water will drip onto the carpet. It's an easy fix, but the car may need to go on a lift to get to the drain tube.

Since a blocked A/C drain tube causes the condensor pan to fill and overflow, which is under the dash on the passenger side, it is hard to understand how a blocked A/C drain tube would wet the rear driver's side floor and not wet the front passenger side floor. I think these are two different issues.
